A kindergarten graduation ceremony at a Victorville elementary school turned ugly Wednesday when several parents got into a fight, causing authorities to place the campus on lockdown.

The incident occurred at Puesta del Sol Elementary School, with officials saying a verbal altercation between two parents turned physical.

“According to witness statements, it appears a few parents went over to a field away from the actual ceremony to discuss something when the alleged fight broke out,” Karen Hunt, spokeswoman for the San Bernardino County Sheriff’s Department Victorville station, told the Victorville Daily Press.

No arrests were made, and no one was hurt in the incident, but the school's principal sent a letter home to parents banning them from the campus.
