According to a report in the New York Times, the fight began when, after going to see a UB40 concert in 1985, Kavanaugh and his friends mistook a man in a CT bar for the band's lead singer, Ali Campbell.
Kavanaugh was accused of throwing ice at someone in the bar, but was not charged with an offense or arrested, police spokesman David Hartman said. Kavanaugh's basketball teammate friend Chris Dudley, who went on to play in the NBA, allegedly threw a glass at the man, cutting his ear.
Cozzolino was treated in hospital for his injuries after he was left bleeding from his ear, according to the police report. Kavanaugh was not arrested, but the police report stated that a 21-year-old man accused Kavanaugh of throwing ice on him "for some unknown reason".
British reggae band UB40 received a burst of unexpected publicity on Monday after reports surfaced that Judge Brett Kavanaugh allegedly got into an altercation at a CT bar in 1985.
"I really believe Kavanaugh is not a gang rapist, a sexual predator, or a stumbling bumbling drunk", he said, adding, "I believe it because I've known him for 20 years".
The White House had questioned the Times' motivation in writing the story because one of its authors, Emily Bazelon, criticized Kavanaugh in July after he was nominated to the court by President Donald Trump.
When asked about Judge Kavanaugh's drinking habits during a news conference on Monday, Mr Trump said he thought his answers during the hearing were "excellent".

The White House did not immediately respond to requests from the Times for comment on Monday. James Roche, Kavanaugh's freshman year roommate at Yale, also spoke out.

Some Democratic lawmakers claimed the White House was keeping investigators from interviewing certain witnesses. He said he may run - either as a Republican or an independent - if no one else does.

He was clear about moving forward. "It was really important, and I thought Earl was a really great man about dealing with it all". Earl Thomas was one piece of the legendary Legion of Boom, but it looks like his time with the Seahawks has come to an end.
What the incident illustrates about Kavanaugh "is just the aggressiveness that came along with the alcohol, the hair-trigger machismo, which was pathetic", he said.
Chad Ludington told NBC News that he was going to the Federal Bureau of Investigation on Monday to give them information about Kavanaugh's drunken behavior when they were classmates at Yale University.
Ali Campbell, the lead singer of UB40, says "It wasn't me!" at a bar in New Haven, Conn. after a concert in 1985.
A White House spokesman did not respond to emails about Ludington's account. I never ever saw Brett black out.
Ludington said the man in question was annoyed by Kavanaugh and his classmates' attention, and got into an altercation with the Yale students, according to a report.
"We weren't drinking water, so it must've been some sort of mixed drink", Ludington told Cuomo.
"It's the type of incident that happens pretty much daily", he said.
He said: "Sometimes I had too many beers, sometimes others did".
In response to her testimony, Judge Kavanaugh said he had never assaulted her or anyone else. Brett drank and I drank.
