Less than a month after being vandalized with pro-Azerbaijani graffiti, San Francisco’s Krouzian-Zekarian Vasbouragan Armenian school was again target of a pattern of hate crimes, when the local police reported that shots were fired at the school building over the weekend, Asbarez reported.

San Francisco police officers were patrolling the KZV Armenian School at around 2:25 a.m. Saturday morning when someone fired a bullet that damaged the school’s sign. No one was injured by the gunfire.

The officers were assigned to guard the Krouzian-Zekarian Vasbouragan Armenian school after the campus was tagged with anti-Armenian graffiti in July and the building adjacent to the St. Gregory the Illuminator Armenian Church was set ablaze last week. An arson investigation is underway.
