Police say De la Cruz is a gang member with an extensive criminal record. He is also reportedly a neighbor of 29-year-old John Matteson, who was previously arrested in connection to the attack and has pleaded not guilty to making criminal threats and other charges with hate-crime enhancements.

Police say the two men approached a group of people who’d just left the mosque late Saturday night and yelled slurs at them, prompting a fight during which one worshipper was stabbed.

The stabbing victim was treated at the Simi Valley Hospital for non-life-threatening injuries.
