Some supporters of Senate President Bukola Saraki held him hostage for about 15 minutes on Saturday after he casted his vote.
Mr Saraki, who is seeking to return to the Senate under the Peoples Democratic Pary (PDP), voted at about 10:30 a.m. amidst praises from scores of his supporters.
He voted at his Polling Unit at 003 Agbaji ward of Ilorin West Local Government Area of Kwara State.
After he voted at about 10:35 a.m., Mr Saraki was barred by his supporters from leaving the polling unit. They demanded election money from him.
He was later allowed to exit the polling unit at about 10:50 a.m as the supporters who demanded money from him were asked to follow the convoy as it is an offence to distribute money at the polling centres.
