LOS ANGELES — Authorities say an explosion outside a synagogue and Jewish school in Santa Monica was caused by a homemade explosive device and not an accident as previously believed.
Police spokesman Sgt. Jay Trisler said Friday that further forensic examination led investigators to conclude the blast that broke windows at Chabad (huh-BAHD') House Lubavitch of Santa Monica on Thursday was intentional.
Trisler says police have linked the device to Ron Hirsch, a transient known to spend time at synagogues and Jewish community centers seeking charity.
Police are searching for Hirsch, whom they describe as "extremely dangerous."
The explosion sent a 300-pound pipe into a house where a child was sleeping and spurred police to evacuate several blocks, but no one was injured.
Investigators earlier said the blast was caused by an industrial accident.
