A 27-year-old Pleasanton resident was arrested Wednesday afternoon on suspicion of brandishing a weapon and making criminal threats, which caused Lydiksen Elementary School to be placed on lock down.
Pleasanton police responded to a residence on Foothill Road, in the vicinity of Lydiksen, after the parents reported their son brandished a knife and threatened to kill them.
The son, later identified as Christopher Kliment, allegedly fled as officers were enroute.
Due to safety concerns and the unknown whereabouts of Kliment, the school on Highlands Oaks Drive was placed on lock down, police said.
"This was precautionary and at no time was there an indication the suspect was an immediate threat or danger to the staff or children," said Sgt. Pat Walsh.
Kliment was located at the West Pleasanton BART station around 1:45 p.m. awaiting a train, according to police reports.
He was detained without incident.
Police said the weapon used in the brandishing was recovered at the residence.
Kliment was booked at Santa Rita Jail in Dublin.
Pleasanton Unified School District officials were notified to life the lock down at 2 p.m.
