Gregg Maloney, an motorcycle officer with the Plymouth Police Department, died of his injuries, after his motorcycle crashed on Samoset Street in Plymouth.

A Plymouth police officer who was injured in a motorcycle crash Tuesday afternoon has died. The crash happened on Samoset Street at about 3:00 p.m.

Colonel Timothy Alben, Superintendent of the Massachusetts State Police, identified the officer as Gregg Maloney. “The @MassStatePolice offer sincere condolences to the Family of Officer Gregg Maloney & our brothers and sisters at the Plymouth PD,” Colonel Alben wrote in a tweet.

Maloney, who was on duty at the time, was traveling westbound on Samoset when he was somehow knocked off his motorcycle. The motorcycle came to a rest about a quarter mile down the road.
