Spokesman for the police, Frank Mba, told TheCable on Monday that Adeleke would be charged to court on Tuesday.
It was learned that the senator had honoured an invitation at the force headquarters in Abuja before he was detained.
“Senator Adeleke is currently in police custody. He was taken into custody in the evening of today 6th May, 2019 in connection with ongoing criminal investigations touching on his person,” Mba said.
“Meanwhile, in the best tradition of natural justice and fair hearing, he has already been served with the relevant charge sheet containing his alleged offences in the presence of his Attorneys. He will be arraigned in a competent court of law tomorrow, 7th May, 2019.”
The police had arraigned Adeleke for alleged examination malpractice.
But his campaign organisation accused the force of working for the ruling All Progressives Congress (APC) over the detention.
