Police on Tuesday were investigating graffiti containing threatening messages found on the walls of a Reseda high school for students with disabilities.

A custodian found the graffiti at Diane S. Leichman High School around 6:30 a.m. Monday and notified Principal Giovanni Trivino, police said.

Hate messages, including “Kill Obama?” had been scrawled in bright blue spray paint alongside pictures of bombs, swastikas and a star of David, according to Trivino. The messages were not aimed at the students, he said.

“LAPD” had been also written, circled and crossed out.

School staff had been on campus Sunday morning and afternoon, which led officials to believe the vandalism occurred Sunday night.

Little of the vandalized area could be seen from the public sidewalk; the school is surrounded by a fence, and the graffiti was found near the back part of the school.

Trivino said it didn’t make sense for political messages to be painted on walls that could hardly be seen by the public.

“We have no idea why we were targeted or why someone would put that on our campus,” he said.

After police had finished investigating the scene, the graffiti was removed or painted over. While the original estimate of damage was reported Monday at about $2,500, Trivino said the estimate should now be closer to $5,000.

No witnesses have come forward and no further evidence was found, said an LAPD official in the West Valley Division. The investigation was ongoing.
