Students at Edison-McNair Academy in East Palo Alto returned to class Wednesday after extensive vandalism to the campus canceled classes Tuesday.
The vandals struck the evenings of Saturday and Sunday, police said, severely trashing the school of 400 fifth through eighth-graders, and also causing damage to nearby Cesar Chavez Academy.
At Edison-McNair, they smashed windows, televisions and computer screens and splashed gang-related graffiti on walls, said principal Ramon Honea.
The vandals also destroyed LED and overhead projectors and stole a laptop.
Vandals also caused some damage at Cesar Chavez Academy, although not enough to shut down the school.
Damages to both schools are estimated at $30,000.
Police arrested a juvenile suspect Tuesday in connection with the weekend vandalisms, alleging the boy left behind a Polaroid photograph of himself at the crime scene.
"He's a former student," said Detective Jeff Liu. "He had no business being at the school."
Liu said police are still searching for more suspects. He said there were no new developments in the case.
Cesar Chavez administrators reported to East Palo Alto police that the Polaroid photo of the boy, apparently self-taken, had been found on campus.
Liu said he could not tell by the picture if it was taken during the commission of the vandalism.
The juvenile was interviewed by police and released to his parents, pending prosecution of burglary and vandalism, Liu said.
