Senator Representing Kogi West Senatorial District in the upper chamber, Dino Melaye, is currently in police custody.
It was gathered that the senator drove to the office of the special anti-robbery squad (SARS) in Abuja to submit himself on Tuesday morning.
The senator had earlier said he will make himself available to the police.
The police have not responded to a request for comments.
The fate of Mr Melaye now that the police have him remain unclear, but Mr Gideon Ayodele, his spokesman said the police planned to take him to Kogi where he has been undergoing criminal investigation, but the senator declined.
“They told us they wanted to take him to court here in Abuja, but they diverted towards Kogi now,” Mr Ayodele said. “But he has said he will not go to Kogi and there is currently a stalemate over that.”
Mr Ayodele said dragging his principal to Kogi would be illegal because the Abuja Division of the Federal High Court had recently ruled that his case should be transfered to Abuja.
The police are after Mr Melaye for allegedly arming deadly criminal gangs and convening a political rally that ended with the death of at least one attendee.
The police also said they had arrested suspects who confirmed that Mr Melaye had provided arms and financial support to them.
There are also allegations that he provided false statement to the police when implicated the chief of staff to Kogi governor in an alleged attempt to assassinate him last year.
Mr Melaye denied the allegations, saying his ordeal was largely because of his outspoken stance against alleged impunity in the country.
He also accused his state governor Yahaya Bello, as the mastermind of his predicament, a claim the governor denied. Mr Bello said Mr Melaye should face the consequences of his actions.
