Police in San Francisco say they have arrested two suspects in Tuesday’s school shooting that left four students injured. The attack, which police say was carried out by four males, happened around dismissal time in the parking lot of June Jordan School in the city’s Excelsior District. Police have now said one of the suspects was arrested Tuesday night and the second Thursday, ABC News reported. The two suspects in custody include the alleged getaway driver and shooter, and police are still searching for two others. Police have said the incident was not random, though it is unclear if one of the four victims was the intended target.
