A man was arrested after opening fire outside a Shake Shack Thursday in the west San Fernando Valley.
The shooter, armed with a handgun, walked up to a window from outside the restaurant and fired about six rounds, police said.
No injuries were immediately reported in the shooting at about noon near Topanga Canyon and Victory boulevards in the Canoga Park area. It was not immediately clear how many people were inside the restaurant at the time.
Stan Thomas, a former U.S. Marine officer, helped police catch the shooter. He'd just pulled into the parking lot, hoping to get a shake, when he heard a popping sound.
