A bomb squad turned up nothing following a bomb threat that prompted the cancellation of classes at Centennial High School in Corona on Tuesday, according to authorities.

The school was rendered safe shortly before 9 a.m., Manny Aguilar of the Corona-Norco Unified School District said. Classes remained canceled for the day as a precautionary measure.

The high school had announced around 6:50 a.m. on Twitter that it had canceled classes due to a “suspicious object” that was being investigated by the Corona Police Department.

A short time later, police said that the cancellation was due to a bomb threat.

Overnight, the high school had received a phone call from a male stating that he had planted two bombs in backpacks on campus and planned to detonate them in the morning, according to a news release from Corona police.

School was canceled for students and staff, and emergency personnel responded to the high school’s campus early in the morning. Officers and bomb detecting K-9’s were called in to conduct a search, the release stated.

After two suspicious backpacks were found on campus, a Riverside County Sheriff’s Department bomb squad responded and detonated the items.

The backpacks were then rendered safe, as was the campus.

“No bombs found,” Corona police tweeted about 9 a.m.

An investigation was ongoing, and anyone with information about the incident was asked to call School Resource Officer Michael Placencia at 951-739-5670 or emailing him at Michael.Placencia@DiscoverCorona.com.
