Livermore High School went on lockdown briefly this morning after police were notified about a possible gun on campus that proved to be a false alarm.
Around 7:10 a.m., someone told police they had overheard two teenage boys on a bus in Livermore both talking about "brass" and one making a hand gesture simulating a gun and pointing to his backpack, police said.
The person thought the boy might have a gun in his backpack and asked the pair where they went to school, according to police.
After the boys said they attended Livermore High School, located at 600 Maple St., and exited the bus, the person gave police descriptions of the students and their bicycles.
Police then contacted officials at the high school and found the two bicycles on campus that matched the caller's description.
As a safety precaution, the school was ordered to shelter in place and administrators sent an email to teachers with descriptions of the boys, police said. A phone alert also went out to parents about the shelter-in-place order.
After the two boys were found in a classroom, it was determined neither had a gun or any weapons.

One boy had used rifle and shotgun shells in his backpack, police said. The lockdown order was lifted 30 minutes later, police said.
Livermore Valley Joint Unified School District Superintendent Kelly Bowers sent a message to parents explaining the situation and what had prompted the lockdown.
"We apologize for any anxiety caused by our initial phone call alert, however we always err on the side of extreme caution in following our safety protocols and in keeping our community informed," the message read.
