Illicit ‘fight club’ busted at LI swim center after gunfire breaks out, leading to over a dozen arrests — some as young as 16

A “fight club’’ was busted at a Long Island swim center Sunday night when gunfire broke out, leading to 13 arrests, cops said.

Suffolk County cops responded to a reported gunshot around 6 p.m. near the Brookhaven Aquatic Center in Shirley and broke up the unauthorized underground fighting ring there, police told Newsday.

One of the participants had pulled out a gun during a scuffle and fired blank shots, which injured two males, ages 17 and 19, cops said. Both were taken to a local hospital.

Most of the people arrested were between the ages of 16 and 20.

One suspect, Devine Brown, 25, of Mastic Beach was charged with assault, menacing, prohibitive use of a weapon and unlawful assembly, police said. He was detained overnight and is scheduled to be arraigned Monday.

Suffolk County Police did not immediately respond to a Post request for additional information.

The incident is the second time police have been called to break up a fight club in Suffolk County in the past few weeks, according to Newsday.

Three men were charged in June after cops busted an unauthorized afternoon brawl, which was advertised on social media and drew about 70 people to Walt Whitman Park in Melville. Most of those in attendance were in their early 20s, cops said.

The notion of illicit organized brawls was popularized by the 1996 novel “Fight Club” by Chuck Palahniuk, which he based off of his own experiences participating in them.

The book was later adapted into the Oscar-nominated film under the same title in 1999 starring Edward Norton and Brad Pitt.
