A security guard was reportedly shot in the arm during the incident. ABC 7, a local station, reported a suspect is in custody.

“The police are investigating this incident,” FRC President Tony Perkins said in a statement released shortly after the shooting. “Our first concern is with our colleague who was shot today. Our concern is for him and his family.”
