The witness insisted that the signature appearing on the document was not his, raising fresh questions about the authenticity of the correspondence.

The Federal High Court in Abuja has granted an application by the defence team of human rights activist and publisher of SaharaReporters, Omoyele Sowore, to subpoena the Director-General of the Department of State Services (DSS), Tosin Ajayi, to testify in the ongoing cybercrime trial over social media posts in which Sowore described President Bola Tinubu as "a criminal."

Justice Mohammed Umar granted the application on Wednesday after the defence argued that only the DSS Director-General could explain the basis for the agency's actions against Sowore and the authority under which the prosecution was initiated.

The ruling came after dramatic testimony by a subpoenaed DSS witness, Uwem Davies, a Principal Officer of the agency, who repeatedly distanced himself from key documents relied upon by the prosecution and said he merely acted on directives from the DSS Director-General.

During cross-examination by Sowore's lead counsel, Adeyinka Olumide-Fusika (SAN), Davies testified that a letter purportedly sent to Meta Platforms, the owner of Facebook, concerning Sowore's social media posts was not authored or signed by him.
