A manhunt has been launched for a shooter who left "multiple victims down" at a California bowling alley.
Police in the city of Torrance, urged people to stay away from Gable House Bowl where it said there had been "shots fired".
Gable House describes itself on its website as a gaming venue that offers bowling, laser tag and a full arcade.
One eyewitness, Jesus Perez, told the LA Times he was inside the bowling alley when the shooting began.
"We just ran right into the bar and took cover. All we heard was just, like two people got shot."
Mr Perez said he thought he had heard about four gunshots and rumours there was a fight before the shooting broke out.
"We just ran into the bar and we just took cover because after the fight we heard 'pop pop'." After taking cover for about 15 minutes, a security guard came to escort him out the back entrance.
