Police officers serving a search warrant as part of a gang sweep in Azusa were met with gun fire Thursday morning.
The sweep was part of a multi-agency operation following a series of gang shootings in the city, Pomona Police Department Chief Michael Olivieri said.
Multiple search warrants were being served in the area, including one in the 5500 block of North Lark Ellen Avenue in which the Pomona SWAT team was assisting, Azusa Police Department Capt. Mike Bertelsen said.
The officers came under fire while attempting to serve the warrant at the front door, Bertelson said.
It was unclear how many shots were fired and how many people may have been shooting from inside the home.
The officers returned fire as they retreated to safety, Bertelson said.
Several residents eventually came out of the home and were being cooperative with authorities, Bertelson said.
Authorities were initially unsure if any additional suspects, or even the shooter, remained inside the home so they sent a robot inside to clear the scene, Olivieri said.
The robot can open doors and send live video back to the officers, he said.
Olivieri later tweeted that the “suspects were in custody” and nobody had been injured.
Several nearby residents had to evacuate their homes during the incident.
