ATHERTON, Calif. — A California school teacher was placed on paid administrative leave after he rattled a table to get the attention of his math students, startling an eighth-grade girl who used her cell phone to call police.

Atherton police Sgt. Tim Lynch tells the Palo Alto Daily News that officers went to Selby Lane School Tuesday afternoon because of reports a teacher was causing a disturbance.

Officers found a calm teacher with class in session.

The sergeant says the teacher’s table-rattling startled a student and she used her cell phone to call 911. He says other students in the class weren’t bothered by the teacher’s actions.

Redwood City School District deputy superintendent John Baker says the teacher was placed on leave because there was a police response.
