The Commissioner of Police, Mr Damian Chukwu, told newsmen in Maiduguri that the command had arrested 24 persons in connection with the killing which occurred on April 15.
Chukwu disclosed that men of the command had recovered the corpse of a 20-year-old welder, Maina Mustapha, at the residence of the politician.
He said the command had earlier declined request by Terab to hold a political meeting at his residence in GRA area of Maiduguri.
“Terab sent a request in a letter with a PDP logo, seeking permission to hold a meeting at his residence in the GRA area.
“The letter was signed by Terab and not by the PDP Chairman or any other official of the party.
“And considering the appearance of a party logo on the letter, we notified him that the command would not permit political gathering within residential areas and advised him to hold the meeting at public places or hotels to enable us to provide security.
“Terab acted against the command’s position, held the meeting at his residence and in the process one persons was stabbed to death,” he said.
The commissioner added that Terab, who was the convener of the meeting, went into hiding and ordered him to report to the nearest police station.
He said that investigation into the case had begun.
