Four members of staff of the Osun State College of Technology, Esa-Oke, who were kidnapped on Tuesday have regained their freedom.
The freed captives were among eight people initially kidnapped on December 4. While three others were freed almost immediately, one other person died on the spot.
The released victims had claimed that the attackers were armed herdsmen who were demanding for an unspecified ransom.
Sources at the school said the gunmen blocked the Esa-Oke Road leading to the campus at about 4:00 pm on Tuesday and stopped several vehicles before abducting some of the occupants.
