Antelope Valley College was set to reopen for night classes beginning at 6 p.m. Tuesday following threats of violence that kept the school shut down all day, authorities said.

The college announced the closure on its website and Facebook page shortly after 8:30 a.m., hours after authorities received reports of possible text threats overnight, according to the Los Angeles County Sheriff’s Department.

The texts said things such as, “Something terrible is going to happen,” according to sheriff’s Lt. Derrick Alsred.

He said the campuses in Palmdale and Lancaster received the possible threatening text.

In a news release, the Sheriff’s Department said calls from students began coming in about 11:50 p.m. Monday regarding texts received from an unknown individual.

“The text message made a vague threat and told the students to stay home from school,” the release stated.

The threats were not believed to be credible but deputies were continuing to investigate, according to the release.

School officials did not provide any details about the alleged threat, but said that the college was in contact with law enforcement.

The school posted an announcement on its website stating classes would resume at 6 p.m. at all AVC locations.

Classes were expected to resume as normal Wednesday, the announcement stated.
