The university's Department of Public Safety said in a news release that student Skylar Williams was in a parking lot at OSU's Mansfield campus shortly before noon Monday when she was approached by a male suspect known to her.
The release says the man displayed a handgun, forced the student into his vehicle and fled with her.
Authorities located the vehicle but are searching for the student and the suspect.
Police say the man also is suspected of stealing a vehicle at gunpoint Monday afternoon. That vehicle is described as a dark 2019 Dodge Caravan with the license plate FMZ-9621.
Anyone with information is asked to contact the State Highway Patrol.
