Police in Lakewood, Colorado, have asked the public for help in identifying a man who was involved in a brawl on the field at a youth baseball game Saturday.

Police spokesman John Romero told media that a game between 7-year-olds from Lakewood and Bear Creek got out of control after parents and coaches got into a dispute over a call by a 13-year-old umpire.

These adults took over the field and began assaulting each other on 6/15 during a youth baseball game. We're looking for any info, in particular to ID the man in the white shirt/teal shorts.

Adults quickly amassed on the field side of the backstop and punches were thrown. Police said several people have already received citations for disorderly conduct and fighting in public, but they are still trying to identify one man in particular.

"There were several reports of injuries and one serious injury," Romero said, according to The Denver Post. "We're looking for any information on this melee, but in particular the identity of the suspect in the white shirt and teal shorts who threw a sucker punch."

Romero said that the man they are looking for likely faces assault charges.
