SAN MATEO, Calif. (KRON) – Four 16-year-old boys were arrested in relation to a shooting at a parking lot at the Hillsdale Mall in San Mateo Wednesday evening, police said in a press release.

The four are residents of San Mateo and were each arrested on charges of assault with a firearm, attempted robbery, and conspiracy to commit a crime — all later booked into Hillcrest Juvenile Hall.

Authorities received reports of the shooting around 5:34 p.m.

Police arrived to find the victim in the lot.

The victim, a 20-year-old San Mateo man, is currently in critical but stable condition, police say. He is expected to survive.

The names of those arrested were not released because they are minors.

Police have not determined the motive of the shooting and are investigating for any other possible suspects.
