A bomb threat that caused temporary evacuations at two Huntington Beach restaurants Saturday night was unfounded, officials said.

The Orange County Sheriff’s Department bomb squad was called to the California Pizza Kitchen and Islands restaurants at the Bella Terra center after a threat was called in to California Pizza Kitchen around 6:17 p.m., Huntington Beach police officials said.

Both restaurants, which are in the 7800 block of Edinger Avenue, voluntarily evacuated, Huntington Beach Police Lt. J. Haught said. The bomb squad searched both restaurants, but nothing suspicious was found, he said.

The restaurants were up and running again a little before 8 p.m. Saturday, Haught said.

The center is near Beach Boulevard and the 405 freeway.
