Update 6:12 p.m.: A D.C. police officer was stabbed multiple times when a man attacked him from behind before he fatally shot his attacker Friday morning, according to police.

Officers responding to reports of a fight between a grandfather and grandson were approaching the grandfather's house, located on the 3500 block of 17th Street NE, at about 6:45 a.m. when a man snuck up behind one of the officers and stabbed him several times in the neck and head, police said.

The officer turned and fired his weapon while being attacked, according to Police Chief Cathy Lanier.

"We believe the suspect was hit instantly," Lanier told reporters Friday morning. "He is deceased here on the scene."

The officer was taken to a local hospital and treated for non-life threatening injuries, police said. He has since been released.

Police are investigating what caused the fight between the grandfather and grandson.

This is pretty traumatic for all the officers that work together," Lanier said. "The last thing we ever want to do is take a life."
