A witness from the Department of State Services, DSS, on Wednesday told the Federal High Court in Abuja that Tukur Mamu, standing trial for alleged terrorism funding, was at no time appointed by the Federal Government to negotiate with terrorists who attacked the Abuja-Kaduna train in 2022.
The witness, an operative of the DSS, said that Tukur sidelined the Chief of Defence Staff Committee set up to negotiate the release of those abducted during the March 28, 2022 train attack.
Led in evidence by DSS lawyer David Kaswe, the witness, whose identity was withheld for security reasons, said the defendant “was not mandated by the government to engage in any form of investigation or negotiation with terrorists, but acted on his own for his personal benefit.”
The witness alleged that the defendant encouraged terrorists to discuss ransom payments with victims, collected money on their behalf, confirmed amounts, and “facilitated payments illegally.”
He further claimed that the defendant benefited financially from the ransom negotiations, possessed firearms unlawfully, and even provided terrorists with information on how to create a website.
He added that huge sums of money recovered from the Kaduna residence of the defendant exceeded the threshold permitted by law, and that the defendant’s lifestyle “changed significantly” during the negotiation period.
“He was arrested in the company of four family members while on a trip to Egypt, and he bought two flashy cars during the negotiation period,” the witness stated.
During cross-examination, defence counsel Johnson Usman, SAN, challenged several aspects of the DSS investigation.
Usman questioned whether the DSS, which has operatives at all Nigerian airports, verified how the defendant and his family travelled to Egypt. The witness replied that he was not aware of their travel details but confirmed that the defendant’s passport was in DSS custody.
When asked if he was a diligent investigator, the witness affirmed that he was, though he admitted he did not open the defendant’s passport during the investigation, stating it was not necessary because he worked with a preliminary report.
The defence also queried inconsistencies regarding the negotiation process. Usman suggested that the terrorists asked victims to propose negotiators, and the victims suggested several names.
The witness agreed that the victims introduced names but insisted that only the defendant (Mamu) agreed to engage with the terrorists, and maintained that the defendant was not part of the CDS committee.
Usman further pressed the witness on hostage releases during the crisis, noting that before the defendant’s involvement, only one hostage had been released.
Meanwhile, Justice Mohammed Garba Umar has adjourned further cross-examination of the witness to January 29, 2026.
