The barricade situation started around 8:15 p.m. Tuesday near 68th Street and Avalon Boulevard after police received a call about a man with a gun. Responding officers found the suspect, who then jumped some fences and ran away from them, according to the L.A. Police Department.
Officers then found him standing next to a car with a rifle inside, but he once again took off. That's when authorities established a perimeter around a junkyard in the area.
Video from the scene shows a large police and SWAT presence as helicopters circled overhead.
A K-9 unit was called out and the dog alerted officers that someone was possibly hiding inside of a shed, the department said. That prompted a lengthy barricade and search overnight.
However, several hours after it began, officers approached the shed and checked inside but nobody was there.
Authorities said a weapon was recovered.
The investigation was ongoing.
