A New Hampshire man was shot and killed by an Old Town Police officer early Thursday .

Adrian Bunker, 37, of Merrimack, N.H., was driving a gray Chevy Silverado pickup truck when he was pulled over by an officer around 3:20 a.m. on Stillwater Avenue, near Pembroke Drive.

“This stop led to an armed confrontation which led to the death of the driver,”Old Town Police Chief Scott Wilcox told reporters during a news conference.

News Center Maine (WCSH-TV) said Bunker was shot and killed by Old Town Police officer Joseph Decoteau.

As is standard procedure in police-involved shootings, Decoteau has been placed on paid administrative leave pending the outcome of an investigation by the Maine Attorney General’s Office, which investigates all police shootings in the state.

Decoteau has been with the department since December 2017.

Old Town police said no officers were injured in the shooting.

Stillwater Avenue was closed for about nine hours, but has since reopened.
