Nigeria’s Department of State Services (DSS) has arraigned a social media user, Mubarak Abdullahi, before a magistrate court in Kaduna State, approximately two weeks after his arrest over circumstances reportedly linked to a purported letter allegedly written by President Bola Tinubu to United Nations Secretary-General António Guterres.
According to an update on the case obtained by ChroniclesReporters, Abdullahi was arraigned on Monday before the Magistrate Court in Kabala Doki, Kaduna State, and remanded in custody pending further proceedings.
The update, however, did not disclose the specific charges brought against him or provide details of the allegations the DSS intends to establish against the social media user.
Information circulating on social media suggests that Abdullahi’s arrest may be connected to a purported letter dated September 19, 2026, allegedly addressed by President Tinubu to the UN secretary-general, seeking diplomatic intervention over his past drug-related case in Chicago, United States.

Sources familiar with the development reportedly indicated that the document forms the basis of the DSS case against Abdullahi. However, the precise allegations against him and the circumstances surrounding his arrest have not been officially detailed in the available update.
The purported letter, titled “Request for Goodwill and Diplomatic Engagement Regarding My Past Drug-Related Case in Chicago,” allegedly appealed to Guterres to engage the United States government, particularly President Donald Trump, on the possibility of intervening in the matter and facilitating the cancellation or closure of the case.
The document reportedly claimed that the matter had continued to attract media attention and public speculation despite having occurred many years ago.
It also referenced Nigeria’s diplomatic relationships with the United Nations and the United States, appealing for what it described as justice, fairness and reconciliation.
However, questions have emerged over the authenticity of the document, with social media posts alleging that the letterhead and signature were forged.
A copy of the purported letter obtained by SaharaReporters was reported to have shown indications that the document was AI-generated, although the available information did not establish an independent forensic verification of its authenticity or identify who allegedly created it.
The circumstances have raised questions about the relationship between the disputed document and the DSS prosecution of Abdullahi, particularly as the specific offences for which he was arraigned have not been disclosed.
The development also comes amid the circulation of allegations concerning the purported letter and its contents on social media. However, the authenticity of the document, the identity of its creator and the extent of Abdullahi’s alleged involvement remain unclear from the information made available.
An update on the case indicated that proceedings were expected to commence during the week, but it did not provide further details about the prosecution’s case or the legal grounds for his continued detention.
As of the time of reporting, the DSS had not publicly disclosed the specific charges against Abdullahi in the available account, and no detailed statement from the agency explaining the basis of the arrest and arraignment had been provided.
