A Honolulu police officer was injured in an early morning gunfight in Nanakuli, Hawaii on Thursday. EMS personnel on the scene treated the wounded 47-year-old officer — who reportedly sustained a gunshot wound to the leg — and transported him to a nearby hospital where he is listed in serious condition.

The suspected gunman was shot and killed in the incident, which began when officers were attempting to serve the suspect with a temporary restraining order.

Police said the man was armed and barricaded himself in the home.

At about 0415 hours, "the suspect exited the home and fired shots at officers according to police," the Honolulu Star Advertiser reports.

Officers returned fire, killing the subject.
