LOS ANGELES (AFP) - Three people were killed and at least a dozen more injured when a shooting broke out after an argument at a pop-up restaurant in Los Angeles, police said on Saturday (Oct 15).

One person has been arrested and police have launched a manhunt for another in connection with the deadly incident in West Adams, in the southwestern part of the metro area, said spokesman Lieutenant Chuck Springer.

Around 1900 GMT (3am on Sunday, Singapore time), investigators were still on scene, and the bodies still inside the home that was temporarily turned into a restaurant.

A woman was taken out and rushed by ambulance to a nearby hospital.

"Today, Los Angeles woke up to a horrifying shooting in West Adams - the latest example of a senseless gun violence epidemic that causes so much pain and sorrow in our city and across the nation," said Mayor Eric Garcetti.

No motive has yet been identified.

"It's a bloody scene with shell casings everywhere," LAPD spokesman Sergeant Frank Preciado told the Los Angeles Times, adding that there were about 50 people in the restaurant at the time of the shooting.

It was a popular Jamaican eatery that often held parties on Friday nights, the Times said.

"Los Angeles grieves for the senseless loss of lives in one of our most cherished neighborhoods. My prayers go out for the victims and their families," Los Angeles City Attorney Mike Feuer added.
