Some supporters of Senate President Bukola Saraki held him hostage for about 15 minutes on Saturday after he cast his vote.
Mr Saraki voted at about 10:30 a.m. amidst praises from scores of his supporters.
He voted at his PU 003 Agbaji ward of Ilorin West Local Government Area.
After he voted at about 10:35 a.m., Mr Saraki was stopped by his supporters from leaving his polling unit. They demanded money from him.
He was later allowed to exit the polling unit at about 10:50 a.m. 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.
