A Denver police officer was arrested Tuesday on suspicion of assault after allegedly crashing his unmarked police car into another car.

38-year-old officer Jacob Marsh will be suspended from the department without pay while his case continues, Denver police spokeswoman Christine Downs said.

Marsh drove his unmarked police car at 3 a.m. on April 13 in the wrong direction on Quebec Street’s 4800 block while following another car, based on the likely cause of his arrest.

Marsh then reportedly collided head-on with another car. The computer system in Marsh’s car indicated he was driving 75 mph in an area with a speed limit of 45 mph. The car allegedly hit by Marsh was driving 51 mph and was going in the right direction, according to the likely cause.

The driver of the car hit was seriously injured and had an operation. The car Marsh was chasing did not stop and was not involved in the accident.

The Denver Police Department did not immediately respond to a question Wednesday whether Marsh was on duty at the time of the crash.
