A three-hour bomb scare at Chaffey College ended with no explosives being found, sheriff’s officials say.

The search began about 1 p.m. Thursday, Aug. 21, with a 911 call from someone who told of a young man carrying a backpack containing a possible explosive device at the campus along the 5800 block of Haven Avenue, said San Bernardino County sheriff’s Cpl. Randy Naquin.

The incident prompted a lockdown and then the cacellation of all classes that were scheduled to begin at 3:30 p.m. or later.

The ground effort included a building-by-building search. During part of the hunt, the crews of two law enforcment helicopters — from the sheriff’s department and Ontario Police Department — checked the campus from the air.

At least one SWAT team participated.

About 4 p.m., sheriff’s officials said the search had ended and the campus was clear of any explosives devices.
