Ex-NFL RB Kevin Smith -- Arrested On College Campus ... After Alleged Car Crash

Kevin Smith -- former Detroit Lions running back -- was arrested on the campus of UCF earlier today ... after cops say he fled the scene of a car accident and then disobeyed a police officer.

According to campus police, the 28-year-old was walking to class (apparently he's back in school) ... when he was approached by a University of Central Florida officer who was investigating a car wreck that occurred over the weekend.

Cops say Smith was involved in the accident and was driving with a suspended license at the time. Officials also believe Smith left the scene without providing information.

Fast forward to Wednesday ... when a UCF police officer tried to issue a citation to Smith -- but he refused to cooperate.

Instead, cops say Smith blew off the officer and continued to walk to class.

That's when the officer decided to "seize" Smith -- and arrested him. He was taken to a nearby jail where, in addition to refusing to sign the citation, he was also charged with resisting arrest.
