US Journalist Identifies 3 Tinubu-Linked Drug Investigation Cases, Raises Possibility of 4th Sealed Case

Washington, September 24, 2026 — American journalist and transparency activist Aaron Greenspan has identified three separate United States legal matters connected to a drug-trafficking investigation from the late 1980s and early 1990s involving records associated with President Bola Ahmed Tinubu and Nigerian businessman Abiodun Agbele.

Greenspan also raised the possibility that a fourth case involving Tinubu could exist as a sealed criminal proceeding. However, he acknowledged that he has no conclusive evidence that such an indictment exists.

The revelations emerged from an interview Greenspan gave to Laolu Akande, founder of Empowered Newswire, published on September 23, 2026.

The issue forms part of Greenspan's continuing Freedom of Information Act (FOIA) litigation in the United States District Court for the District of Columbia, through which he is seeking historical records from US agencies, including the FBI and Drug Enforcement Administration (DEA).

Importantly, the ongoing FOIA lawsuit is a civil dispute over access to government records, not a criminal prosecution of Tinubu.

Three Cases Identified by Greenspan

According to Greenspan, the three matters connected to the wider investigation consist of:

A series of 1992 criminal indictments involving members of the alleged drug-trafficking network;

A separate matter involving Nigerian businessman Abiodun Agbele; and

A 1993 civil forfeiture proceeding involving approximately US$460,000 held in an account in Tinubu's name.

Greenspan said these matters should be viewed as connected to the same broader investigation, rather than described simply as three criminal cases against Tinubu.

“There’s at least three known cases now that are tied to this drug ring,” Greenspan said in the interview.

1992 Criminal Indictments

The first matter concerns criminal indictments brought in 1992 against individuals allegedly connected to the drug-trafficking network under investigation by US authorities.

Greenspan said transcripts relating to those proceedings are available in the US National Archives.

The existence of those indictments, however, does not by itself establish that Tinubu was a defendant in the 1992 criminal cases.

That distinction is important when reporting the historical records because the wider investigation involved several individuals and alleged activities spanning the United States, Nigeria and other countries.

The Abiodun Agbele Matter

The second matter identified by Greenspan concerns Nigerian businessman Abiodun Agbele.

According to Greenspan's account, Agbele was linked to the same broader investigation and appeared in historical records concerning an alleged heroin-trafficking network.

Greenspan cited testimony involving DEA Special Agent Vincent Balbo and a criminal proceeding involving Lee Andrew Edwards.

He said historical records described Agbele as being involved in supplying heroin to Edwards' organisation.

Greenspan also said that searches of publicly accessible US federal court records have not located a readily available criminal case against Agbele, leading him to investigate whether some related records could remain sealed.

However, the absence of a publicly accessible case does not by itself prove that a sealed indictment exists.

The US$460,000 Civil Forfeiture Case

The third matter is the case most directly associated with Tinubu's name.

It concerns approximately US$460,000 held in a US bank account in Tinubu's name, which American authorities sought to forfeit in 1993.

The proceeding was a civil asset-forfeiture case, rather than a criminal prosecution resulting in a conviction of Tinubu.

According to records cited in the FOIA litigation, US authorities alleged that the funds were connected to proceeds of narcotics trafficking or transactions prohibited under US law.

The funds were ultimately forfeited to the United States.

The distinction between civil forfeiture and criminal conviction is significant: the existence of the forfeiture proceeding does not establish that Tinubu was criminally convicted of drug trafficking.

Greenspan Raises Possibility of a Fourth Case

Greenspan said his examination of historical records has raised another question: whether a separate criminal indictment involving Tinubu could have been filed under seal.

“There could be a fourth,” he said, referring to the possibility of a criminal indictment involving Tinubu.

But Greenspan also acknowledged that he has not established that such an indictment exists.

He said the possibility arose partly because of the level of detail contained in some of the historical investigative material he has reviewed.

The records, according to Greenspan, contain extensive information concerning financial accounts and individuals connected to Tinubu.

He suggested that the available material could be consistent with more than one explanation: authorities may have investigated the matter extensively without ultimately bringing charges, or a proceeding could potentially have been filed but remained inaccessible to the public.

For now, however, the alleged fourth case remains unverified.

What the US FOIA Case Is Actually About

Greenspan's wider legal battle began after he filed FOIA requests seeking historical records from US government agencies concerning investigations involving Tinubu, Agbele and others.

The case, Greenspan v. Executive Office for U.S. Attorneys et al., Case No. 1:23-cv-01816-BAH, is being heard in the US District Court for the District of Columbia.

The lawsuit concerns access to government records.

It is therefore important not to characterize the FOIA proceedings themselves as a criminal case against Tinubu.

In an April 8, 2025 ruling, US District Judge Beryl Howell addressed Greenspan's requests for records and the government's handling of the information.

The litigation has continued over what records should be released and which portions can legally remain withheld or redacted.

According to the latest reporting, the FBI and DEA have produced hundreds of pages of records, with some information withheld under exemptions relating to matters such as grand-jury secrecy, confidential sources, investigative techniques and personal privacy.

Why the Distinction Matters

The renewed controversy has generated headlines suggesting that three drug cases exist against Tinubu.

The available information requires a more precise description.

The three matters identified by Greenspan are connected to a broader historical drug investigation, but they are not equivalent to three criminal convictions or three criminal prosecutions against Tinubu.

The 1992 indictments involved alleged members of the wider network.

The Agbele matter concerns another individual connected to the investigation.

The US$460,000 proceeding involving Tinubu was a civil forfeiture case.

And the alleged fourth criminal case has not been established.

These distinctions are particularly important because criminal allegations involving a sitting president carry significant legal and political implications.

Tinubu's Position and the Need for Documentary Evidence

The historical allegations surrounding Tinubu have been disputed by Nigerian government officials and his representatives.

The Presidency has previously emphasized that the US litigation involving Greenspan is a records-access case rather than a criminal prosecution of the Nigerian president.

The existence of a civil forfeiture proceeding involving funds in an account bearing Tinubu's name is a matter reflected in historical US court records. But the legal nature and outcome of that proceeding should not be conflated with a criminal conviction.

Similarly, claims about a possible sealed indictment require documentary confirmation before they can be treated as an established fact.

What Happens Next?

Greenspan's continuing FOIA litigation could potentially result in the release of additional historical records.

If further documents are unsealed or released, they could clarify what US investigators knew, which individuals were formally charged, how the different cases were connected and whether any additional proceedings existed.

Until such evidence becomes publicly available, the claim that a fourth sealed criminal indictment against Tinubu exists remains a possibility raised by Greenspan, not an established fact.

Factful24 Verification Note

The latest development centers on claims made by Aaron Greenspan in an interview and documents associated with his US FOIA litigation.

Established from the available reporting:

There were historical US criminal proceedings involving members of a wider drug-trafficking investigation.

Records concerning Abiodun Agbele form part of the historical investigation.

A 1993 civil forfeiture proceeding involved approximately US$460,000 in an account in Tinubu's name.

Greenspan is pursuing the release of historical US government records.

Not established by the available evidence:

That Tinubu was convicted of drug trafficking.

That the three identified matters constitute three criminal cases against Tinubu.

That a fourth sealed criminal indictment against Tinubu exists.

Factful24 will continue to distinguish between court-established facts, allegations, statements by interested parties and unresolved claims as further records emerge.
