US Journalist Identifies Three Cases Linked to Tinubu-Related Drug Investigation, Raises Possibility of Sealed Fourth Case
ABUJA — American journalist and transparency activist Aaron Greenspan has identified three separate US cases connected to a drug-trafficking investigation from the late 1980s and early 1990s involving records related to President Bola Ahmed Tinubu and Nigerian businessman Abiodun Agbele.
Greenspan also raised the possibility of a fourth criminal case involving Tinubu that may have been filed under seal, but acknowledged that he has no conclusive evidence that such an indictment exists.
Greenspan made the disclosure in an interview with Laolu Akande, founder of Empowered Newswire, published on September 23, 2026.
The three matters he identified are distinct and should not be described simply as “three criminal cases against Tinubu”.
1. 1992 CRIMINAL INDICTMENTS
Date: 1992
The first matter comprises a series of criminal indictments involving alleged members of the drug-trafficking network investigated by US authorities.
Greenspan said transcripts relating to the 1992 indictments are available in the US National Archives.
The investigation concerned an international drug-trafficking and money-laundering organisation that operated in the United States during the late 1980s and early 1990s.
Importantly, the available records do not establish that Tinubu was a defendant in those 1992 criminal indictments.
The matter should therefore be reported as a criminal prosecution involving alleged members of the wider network, rather than as a criminal case against Tinubu.
Outcome: Criminal proceedings were brought against identified members of the network. The available evidence does not establish a criminal conviction of Tinubu arising from the 1992 indictments.
2. THE ABIODUN AGBELE CASE
Period: Early 1990s
The second matter concerns Nigerian businessman Abiodun Agbele, whom US law-enforcement records identify as having been investigated in connection with the drug-trafficking organisation.
A US federal court's 2025 ruling in Greenspan's Freedom of Information Act case records that a 1993 Justice Department forfeiture complaint and accompanying affidavit publicly disclosed details of a DEA investigation involving Agbele.
According to the affidavit, DEA investigators said Agbele sold heroin to an undercover law-enforcement officer following an undercover operation.
The court specifically found that the existence of a DEA investigation of Agbele had already been officially acknowledged through publicly filed government documents.
Greenspan describes this as a separate criminal case connected to the wider drug network.
Outcome: Agbele became a subject of the US drug investigation and cooperated with investigators, according to the account presented by Greenspan. The available material does not establish that Tinubu was criminally charged or convicted in Agbele's matter.
3. THE 1993 US$460,000 CIVIL FORFEITURE CASE
Date filed: July 26, 1993
The third matter is the most directly connected to Tinubu's name.
The case was filed in the US District Court for the Northern District of Illinois as:
United States v. Funds in Account 263226700 Held by First Heritage Bank in the Name of Bola Tinubu, Case No. 1:93-cv-04483.
It was a civil asset-forfeiture proceeding, not a criminal prosecution.
US authorities sought forfeiture of approximately US$460,000 held in an account in Tinubu's name, alleging a connection between the funds and proceeds of narcotics trafficking.
The case was resolved through a settlement, with the funds in question ultimately forfeited to the United States.
A subsequent federal court opinion in the Greenspan FOIA litigation confirms the existence of the 1993 forfeiture complaint and the government's investigation involving Tinubu.
Outcome: Approximately US$460,000 was forfeited to the US government. The proceeding itself did not constitute a criminal conviction of Tinubu.
WHAT THE 2025 US COURT RULING ESTABLISHED
The distinction between the cases is particularly important.
In an April 8, 2025 ruling in Greenspan v. Executive Office for US Attorneys et al., the US District Court for the District of Columbia examined Greenspan's FOIA requests for FBI, DEA and CIA records relating to Tinubu and Agbele.
The court found that publicly filed government documents had already officially acknowledged that Tinubu was a subject of a criminal investigation involving the FBI and DEA.
The court consequently ordered the FBI and DEA to search for and process non-exempt records responsive to Greenspan's requests. The CIA, however, was allowed to maintain its refusal to confirm or deny whether responsive records existed.
The ruling was not a criminal judgment against Tinubu. It concerned access to government records under the US Freedom of Information Act.
POSSIBILITY OF A FOURTH SEALED CASE
Greenspan has now raised the possibility of a fourth criminal proceeding involving Tinubu.
His theory is based on his examination of historical records and the fact that some information remains unavailable or protected under US law.
However, Greenspan has not produced a sealed indictment or other conclusive evidence establishing that such a fourth criminal case exists.
He therefore presents it as a possibility requiring further investigation rather than an established fact.
THE BOTTOM LINE
The three matters identified by Greenspan should therefore be understood as follows:
- 1992: Criminal indictments involving alleged members of the wider drug-trafficking network — not established as a criminal indictment against Tinubu.
- Early 1990s: Criminal investigation/proceeding involving Abiodun Agbele — not established as a criminal conviction against Tinubu.
- 1993: Civil forfeiture proceeding involving approximately US$460,000 in an account in Tinubu's name — funds forfeited, but the proceeding was civil rather than a criminal conviction.
- Possible fourth case: A potential sealed criminal proceeding involving Tinubu — unverified and not established by publicly available evidence.
The distinction matters because describing these matters simply as “three drug cases against Tinubu” would overstate what the available court records establish.
The ongoing US FOIA litigation may provide additional information if further records are released.
The Analyst Online Media will continue to monitor the proceedings and report developments based on court records, official documents and attributable statements, while clearly distinguishing established facts from allegations, interpretations and unverified claims.
