When firefighters with the Henrietta Fire District responded to a call for an overcrowded bar early Sunday morning, they had no idea what was about to happen.

Lt. Jared Guhl, who was not at the scene but debriefed with the firefighters who had been on duty overnight, said the massive brawl that unfolded about 1 a.m. outside Schramrocks Irish Pub at 200 Park Point Drive in Henrietta near Rochester Institute of Technology was unexpected.

"We can't treat every call as routine," Guhl said. "We were kind of amazed at what transpired."

In a post on Facebook, Henrietta Fire District Chief Mark Strzyzynski shared a retelling of that brawl: The fire department had been called in to assist with the bar being over occupancy, but when Engine 642 arrived, more than 200 people had spilled out of the bar and into the parking lot in a massive and chaotic fight.

"Our firefighters retreated to the engine, however they could not escape the scene due to the large fight and chaos in the parking lot," Strzyzynski wrote in the post. "While our Firefighters were not directly involved they did feel they were in an extremely dangerous environment and called for additional law enforcement help."

The Monroe County Sheriff's Office also responded to the scene, spokeswoman Amy Young said in a news release. The Brighton Police Department arrived moments later and began breaking up fights and detained one person for criminal mischief, Young said.

In the Facebook post, Strzyzynski credited police for rescuing the firefighters.

"Help quickly arrived and was able to secure a perimeter around our engine company and eventually disperse the violent crowd," Strzyzynski wrote. "No Firefighters were injured and the only damage to our property was blood splatter on the engine."

As sheriff's deputies broke up the crowd, they received a report from Strong Memorial Hospital that multiple people with stab wounds had come from that location, Young said in the release.

Three victims were identified and spoken to at the hospital, Young said, adding that all three were uncooperative and did not wish prosecution. No arrests were made, she added.

Police scanner audio of the brawl was shared on Facebook. Firefighters with the Henrietta Fire District can be heard explaining the situation and then asking for help when the group of people fighting got too close.

"Yeah, there's about 15 brawls going on out here in the parking lot," someone says on the scanner. "Be advised, my vehicle's under attack out here. ... Page me an ambulance, please."

In his Facebook post, Strzyzynski said no firefighters were injured but that they risk their lives and their safety on a daily basis to help others in their community.

"This is to inform the public of the risks our Firefighters, EMTs and Law Enforcement Officers face on a daily basis," Strzyzynski wrote in the post. "Thank you to the MCSO for rescuing our crew."
