Authorities arrested a woman on suspicion of trespassing and assault with a firearm after she holed herself up in a resident’s garage for about four hours Monday afternoon, police said.

A man called police at about 3:30 p.m. reporting a woman had pointed a gun at him and then entered his garage in the 1000 block of Grand Avenue in the Zaferia area, police said.

Police said they believe man and woman did not know each other.

After establishing a perimeter, police ordered nearby residents to evacuate or shelter in place while a SWAT team attempted to arrest the woman.

“Officers made contact with the suspect, and negotiators attempted to deescalate the situation for several hours, but the suspect refused to surrender,” said LBPD spokesperson Richard Mejia.

The woman, identified by police as Ashley Nichelle Inscho, 32, of Long Beach, exited the garage after about four hours, Mejia said, and officers used a “chemical agent and an arrest hold” to take the woman into custody.

After being medically cleared for her injuries, the woman was booked on one count of assault with a firearm and trespassing, with bail set at $50,000.

Police have not identified a motive.
