Sheriff’s authorities evacuated people from a Valencia McDonald’s and shut down part of McBean Parkway on Sunday afternoon after an employee found a suspicious-looking device, which was later confirmed to be a fake bomb left in the women’s bathroom.

The Santa Clarita Valley Sheriff’s Station received the employee’s call around 1:30 p.m., said Lt. Tom Bryski.

“We got there and confirmed that the device looked like an explosive device,” Bryski said.

Officials evacuated the McDonald’s in The Promenade shopping center and shut down about a block of McBean Parkway near Creekside Road, as they called in an arson-explosives team.

“They ended up detonating it; apparently there wasn’t an explosive charge attached to the device,” Bryski said. “It was a replica.”

The device looked exactly like a homemade bomb, he said.

Investigators were viewing surveillance tapes Sunday evening to determine who might have abandoned the device, Bryski said.
