Eight members of the FDNY were reportedly suspended for participating in a drunken firefighter-on-firefighter brawl outside a Bronx bar over the weekend.

Sources tell NBC New York that seven firefighters and one lieutenant—members of Engine 68, Ladder 49, Ladder 44 and Rescue 3—were hit with 30 day suspensions without pay over the incident, which allegedly began when one firefighter called another the n-word at Billy's Bar, near Yankee Stadium. On Thursday, the fire department released a statement saying they'd launched an investigation and "since obtained disturbing video that we have shared with the city’s Department of Investigation."

A DOI spokesperson could not confirm that an investigation had been initiated.

"Everyone and anyone who engaged in this outrageous behavior will be held accountable," Fire Commissioner Daniel Nigro said last week.

Video (above) posted to Instagram shows the aftermath of the clash, in which a group of visibly plastered off-duty firemen are confronted by NYPD officers, one of whom appears to get shoved by a firefighter.

"They've been doing that all day—they just had a big fight right here," the cameraman shouts in the video. "America, man. They wanna lock me and you up for one argument, but they can do whatever they want."

A source told the Daily News that the fight went down during a celebration for firefighter Matthew Murphy of Rescue 3, who'd been awarded both the Vincent J. Kane Medal and the Brummer Medal earlier in the day. "They were drinking since 11 a.m.," the source said. "They show up at the bar after the medal ceremony and they got out of hand. The ladder and engine guys were fighting with the Rescue 3 guys."

Bouncers at the bar reportedly had to use mace on at least one firefighter. No arrests were made at the scene. On Thursday, the NYPD said in a statement, "There are no formal complaints on file and the NYPD is currently looking into the incident. Furthermore, responding officers arrived on scene and dispersed the crowd. Officers did not report hearing any slurs or encountering anyone with injuries."
