A Los Angeles cop shot and killed a combative vandal wielding a metal chair when he reached for an officer’s gun during a hospital scuffle, authorities said.

The unidentified 26-year-old suspect died about a half hour after he was shot once at the Harbor-UCLA Medical Center, a visit that started when he “viciously attacked” two officers outside an apartment building where police said he was throwing bottles.

He managed to punch, kick the officers and knock a stun gun out of an officer’s hand during the fight. The alleged assailant was eventually subdued and hospitalized with minor injuries.

But the suspect’s demeanor changed completely while handcuffed to a gurney at the hospital.

He was “very cooperative, very somber,” Los Angeles Police spokesman Phillip Tingirides said at a media briefing late Saturday.

A pair of officers assigned to watch over the suspect did not realize he would unleash another attack the moment they unhooked his handcuffs from the hospital bed.

“There wasn’t an expectation on the officer’s part that he would attack again like that,” Tingirides added.

A 26-year-old suspect who reportedly attacked police was shot and killed on Dec. 19, 2015, at this scene, outside Harbor-UCLA Medical Center in Torrance, California.

 

An officer tried to stun the suspect wielding the chair during the 2:30 p.m. scuffle, but the darts failed to incapacitate the suspect.

He instead opened fire and hit the suspect with one shot as he reached for his partner’s firearm.

The hospital’s staff began treating the suspect for a gunshot wound to his chest immediately after he was shot, according to the Los Angeles Times.

He was bound for a jail transport when he attacked the officers a second time, officials added.
