Mentor police have arrested a suspect in connection with a hit-and-run that killed one of their own.

The person is being questioned by police, but has not yet been charged, according to authorities.

The officer sustained serious injuries in a hit-and-run around 1 a.m. on Sunday on State Route 2 just east of State Route 306, according to police. He was hit while assisting with a traffic stop. The officer was taken to TriPoint Medical Center where he was pronounced dead.

According to a press release issued by the city, the officer, who has not been identified, was struck by what is believed to be a late model Jeep Wrangler. It is said to be dark in color and would have sustained damage to the front right side and possibly the right side.

News 5 was at the Mentor Lagoons Marina as police went through a vehicle matching the one involved in the deadly crash. Mentor police have not confirmed whether or not this is in fact the vehicle from the Sunday morning crash.
