SANTA MONICA, Calif. — Authorities locked down Santa Monica College on Tuesday after at least three people reported seeing a gunman on the Southern California campus, an official said.

The calls came in around 11 a.m. and police immediately ordered staff and students to stay indoors, college spokesman Bruce Smith said.

Police were trying to determine if the reports were genuine or if any shots had been fired, Smith said. A call to the Santa Monica Police Department was not immediately returned.

The college is a two-year community college with about 30,000 students.

School is not in session but teachers and some incoming freshmen are on the college grounds.

Smith said the college sent an email to all employees about the lockdown but was awaiting further instruction from police before activating a text messaging alert system.
