A tear gas canister ignited a fire at a City Terrace area home surrounded by SWAT officers as part of a standoff Wednesday morning, according to sheriff's deputies.
The alleged gunman was not in the house.
The standoff, in the 1000 block of North Alma Avenue (map), began about 2 a.m. after a woman reported that a family member discharged a gun.
"We received a call of a person firing his gun," said Los Angeles Sheriff's Department Sgt. Jose Uribe. "We're trying to make contact with the subject."
The fire, later attributed to tear gas, started about 8:45 a.m. and was extinguished shortly after 9 a.m. Aerial video showed firefighters on the roof and walking in and out of the home.
The man was believed to be the only person in the house at the time, Uribe said.
When officers arrived, the man's mother said she had argued with her adult son and that he was holding a gun, Los Angeles County sheriff's Deputy Irys Alvarez said.
The woman said her son went into his bedroom and fired the weapon, Alvarez said, adding that the gun was discharged prior to deputies' arrival.
The man was seen walking inside the residence, but he disregarded commands to come out, she said. A SWAT team was summoned, and nearby residences were evacuated.
