An intruder or intruders used bolt cutters to enter a fenced area and open approximately 100 lockers at Palo Alto High School, according to Palo Alto police.
The entry occurred between Friday, March 30, and Sunday, April 1, when a teacher reported the situation, Palo Alto Police Agent Marianna Villaescusa said.
Paly students and staff vacated the campus for spring break after school Friday and are scheduled to return Monday, April 9.
Villaescusa said nothing has been identified as missing because "everybody's out for the holiday." She said she did not know whether a security patrol had been operating on campus over the weekend. The police have no suspects, she said.
