Santa Monica police said an explosion that sent an object hurtling onto the roof of a home near a Jewish school and prayer house was an accident — not a bomb.
Sgt. Jay Trisler said a mechanical failure caused a pressure buildup resulting in the blast.
Sgt. Marty Fine said the blast shattered windows at the Chabad House Lubavitch of Santa Monica and launched an object onto the roof of a building next door. TV reports showed a hole in the roof with a long cylinder poking out.
No injuries are reported. Fine said about 100 people have been evacuated from a four-block area while bomb experts investigate.
