LOS BANOS, Merced County (CBS SF) – A high school in the Central Valley was vandalized with presumptive Republican presidential nominee Donald Trump’s name, along with campaign slogans on Cinco de Mayo.

Custodians at Los Banos High School cleaned up most of the vandalism before class began Thursday, but not before students shared pictures of the graffiti on social media, CBS affiliate KGPE-TV in Fresno reported.

School officials said surveillance cameras captured up to five people who were on campus early Thursday morning.

“The custodian told me that they figured he had probably hit about 80 percent of the campus which is quite a bit”, assistant superintendent of secondary education Paul Enos told the TV station.

According to school officials, the graffiti included sayings such as “build a wall” and “Make America Great Again,” Trump’s campaign slogan. Vandals also wrote a derogatory statement about Sen. Ted Cruz, who dropped out after Tuesday’s primary in Indiana.

“Having it be the night before Cinco de Mayo is a little too coincidental,” Enos said.

“I think it’s pretty disrespectful to the high school,” said student Dylan Mejia-Rodney.
