In an announcement on Monday, the battle association said Adeleke had regarded a welcome at the power base camp in Abuja before he was kept.

He landed at the power home office at 9am and was not taken care of until later this evening when he was educated regarding crisp charges of tribute phony. The recognized Senator was taken to Maitama Police station with plan to charge him tomorrow at an undisclosed Magistrate court."
