LANCASTER (CBSLA.com/AP) — Antelope Valley College in Lancaster reopened after closing its main campus and two satellite locations as sheriff’s detectives investigate a threat of violence made on social media, officials said Tuesday.

Evening classes were expected to proceed as normal.

Spokeswoman Elizabeth Diachun says there was nothing specific about the threat that circulated early Tuesday. She says school officials decided to cancel all daytime classes out of an abundance of caution.

Multiple Antelope Valley College students received threats via text message, according to Los Angeles County Sheriff’s Lancaster Station investigators.

The main campus and a separate office in Lancaster were closed, as was a location in Palmdale. Sheriff’s investigators are at all locations.

Darrell Mardirosnian, who is a parent of two students at the school, told KNX 1070 NEWSRADIO such security threats are rare.

“The campus is actually pretty quiet,” said Mardirosnian. “There was a threat a couple years ago that turned out to be nothing, but it’s a very quiet community up there.”

The closures came on the heels of another reported suspicious item at Mount SAC in Walnut that authorities say was later determined to be a casserole dish with a note inside that read, “Thanks for the good dish.”
