Brentwood Police arrested a former Heritage High School staff member after he showed up to a football game Friday evening despite being ordered to stay away from the campus.

Carlos Hurtado, 27, of Oakley, was booked into the Martinez Detention Facility for disrupting a school activity, trespassing, and obstruction charges.

The school’s principal flagged officers who were already working at the game around 7:25 p.m. after Hurtado showed up to the match between Heritage High School and Granada High School, Brentwood Police said.

When officers approached Hurtado, he started running through the stadium. Police officers chased after him, but ultimately a bystander put an end to the pursuit by tackling Hurtado. No officers or bystanders were injured.

A local journalist, Mike Burkholder of the East County Today account and Contra Costa News website, posted what he said was a video of the incident on his YouTube account.

Hurtado is listed on the Heritage High website as the head junior varsity boys soccer coach. Police did not say why Hurtado’s employment was terminated or why he was banned from visiting the school campus. The superintendent of Contra Costa County’s Liberty Union High School District, which oversees Heritage High, could not immediately be reached for comment.

A Carlos Adrian Hurtado Facebook account had a post Friday addressed to “members of the Oakley Brentwood community” that said he’s “been in the Liberty Union High School District for 6 full years.”

“However, my seventh year has been quite a nightmare,” the post, which could not be verified, continued. “I am in desperate need of your support in order for me to continue getting back to my community.”

The post included an online petition to “Bring back Mr. Hurtado” that was signed by 115 people.
