The Nigeria police have arraigned Aminu Mohammed, a final-year student of the Federal University, Dutse, Jigawa, who was arrested by security operatives for allegedly criticizing the first lady, Aisha Buhari.

The police had earlier told Mr Mohammed’s family that he would be arraigned on Tuesday but later postponed the arraignment till Wednesday on the premise that the judge was indisposed.

According to Daily Nigerian, the police later on Tuesday arraigned the final-year student before FCT High Court No. 14.

According to his uncle, Shehu Baba-Azare, the police did not inform the family about the arraignment.

“It’s clearly a secret arraignment because they did not inform us. We are very concerned about his situation. He will sit for his final exam on December 5,” Mr Baba-Azare said.

Mr Mohammed was picked up a few days ago by plainclothes policemen over a Twitter post criticising the first lady.

Mr Aminu was allegedly beaten up alongside a former social media aide to the first lady, Zainab Kazeem, for allegedly leaking secrets of the first lady.

The president’s wife reportedly fractured her leg while trying to join the security agents in brutalizing the duo.

While Mrs Kazeem was released and asked not to speak to anyone about her ordeal, Mr Mohammed remained in police custody until his secret arraignment on Tuesday.

Their arrest and torture have sparked nationwide outrage, with many accusing Mrs Buhari of abuse of privilege.
