BRENTWOOD -- Two high school students suffered stab wounds after a fight broke out Thursday afternoon at City Park, police said.

According to Brentwood police Sgt. Bryan Smith, around 2:14 p.m., officers responded to Brentwood City Hall for reports of a stabbing. The stabbing allegedly happened after a fight between two Liberty High School students and an Independence High School student.

When officers arrived, they found a 17-year-old male Brentwood resident at Pine and Second streets, bleeding from stab wounds to his head and his side.

A 16-year-old male Brentwood resident was found at Diablo Way near Pine Street, also suffering from a stab wound to the head.

The 17-year-old was taken to John Muir Medical Center in Walnut Creek and the 16-year-old was taken to Sutter Delta Medical Center in Antioch.

Both teens are expected to survive, Smith said, and a 16-year-old has been arrested in connection with the stabbing.

However, according to Brentwood police Chief Mark Evenson, based on witness accounts the stabbing may have been self-defense.

The investigation into the incident is ongoing. Anyone with information can call Brentwood police at 925-778-2441 or 925-634-6911.
