Two Los Angeles County Sheriff’s deputies were shot Thursday night in Bellflower, and residents in a one-square mile area were asked to shelter in place during the search for the gunman early Friday.

The shooting took place in the 9000 block of Oak Street about 10:50 p.m., the Sheriff’s Department said.

The deputies were manning a DUI checkpoint at Lakewood Boulevard and Oak Street, said Capt. Christopher Reed. It was unclear if they initiated a traffic stop or followed a vehicle, but they were fired upon by at least one man in the vehicle.

Responding deputies were also fired on, said Reed, though it was unclear if it was the same man or an additional gunman. Deputies exchanged gunfire with the suspect or suspects, and two deputies were hit.

The shooting took place near the intersection of Lisa and Laurel Streets, Reed said.

The gunman was still at large, and a one-square-mile area was contained. Two homes on Mayne Street were evacuated, Reed said, and residents in the containment area were asked to shelter in place.

The wounded deputies were taken to hospitals. The Sheriff’s Department tweeted about 2:25 a.m. Friday that both are in fair condition and are expected to survive,

Anyone with information was asked to contact Los Angeles Crime Stoppers at 800-222-TIPS.
