Killed: Authorities said Maj. Greg Barney (pictured) was taken to Southern Regional Medical Center in critical condition after being shot on Thursday. He was taken into surgery but did not survive.
A Georgia police was gunned down during a drug operation in an Atlanta suburb on Thursday, before cops shot dead the suspect.
Riverdale police officers were assisting Clayton County police with an operation at an apartment complex in Riverdale late Thursday morning, Riverdale police Assistant Chief Michael Reynolds said at a brief news conference.
The officer has been identified as Maj. Greg Barney, who was reportedly not wearing a bullet-proof vest at the time of the incident, WSBTV reported.
He is the fifth cop to be killed in the U.S. in the past 24 hours, and the fifth this week.
Barney was part of a team serving a no-knock drug warrant around 11.15am at the Villages on the River, an apartment complex in the 6600 block of Church Street.
Instead of surrendering, the male suspect ran out a back door.
'He ran approximately 100 to 200 feet from the incident location and we had officers from Riverdale on the perimeter,' Clayton police Chief Michael Register told The Atlanta Journal-Constitution.
'He confronted one of the Riverdale officers and shot the officer in the torso.'
The Riverdale officer was struck twice by gunfire, police said.
The suspect then fled but was confronted at the front of the apartment complex by another officer.
The suspect was shot and subsequently died. He has not been named.
