Lockdowns lifted at two schools in San Dimas after call of man with gun

Authorities Thursday searched the campuses of San Dimas High School and nearby Lone Hill Middle School after an anonymous call was received alleging the presence of a man with a gun, but no such person was found.

"All clear at San Dimas High School," the San Dimas Sheriff's Station tweeted about 11:15 a.m.

"There were anonymous calls from one source about a person with a gun on campus. No weapon was found, there was no actual sighting of a person with a gun. There were no injuries. This investigation continues, but we have... clear indications this was a prank call," the statement said.

After the calls were received, the schools had been placed on lockdown.
