The Nigeria Labour Congress has hired forensic experts to comb its national secretariat in Abuja for possible bugs planted by the police.

The union said the forensic security audit would facilitate the return of its workers to their offices following the recent raid by the police.

Newsmen reported that security agents, on July 7, conducted a night raid on the NLC national secretariat in Abuja.

According to the NLC spokesperson, Benson Upah, the operatives burst into the building at about 8.30 pm and arrested the security guards, forcing them to hand over keys to the offices on the second floor.

The police took responsibility for the operation, saying it was aimed at uncovering incriminating documents that could help build a case against an international “subversive” figure considered a threat to Nigeria’s democracy.

Last week, the NLC rejected the explanation offered by the police on the raid and demanded the release of its arrested members and seized documents.

The National Assistant General Secretary of NLC, Chris Onyeka, said the union had hired foreign experts to comb the office for possible bugs planted by the police.
