Police used a stun gun on at least one man when a brawl broke out among angry parents who couldn’t watch their kids graduate high school Friday, according to Channel 2 Action News.

Dozens of parents told the news station they were stuck outside when the Tri-Cities High School's graduation was moved indoors because of the rain.

Parent Wajeedah Price told Channel 2 it was ridiculous to be stuck outside when the gymnasium couldn’t hold all the attendees.

“This is a once in a lifetime moment, and we can’t see our kids graduate,” Price said.

The change caused chaos outside.

“It was pushing and shoving, and don’t push me, don’t push, next thing you know, swings, arms, fists,” parent Janelle Carter said.

Arriving early wasn’t a solution, either, one parent told Channel 2.

Chet Boykin, who arrived two hours early, said he would have decided to hold the event another night.

“I was here at 5:30 p.m., and we still couldn’t get in,” Boykin said. “They should’ve stopped it and scheduled it for another day.”
