STAMFORD — A city man sustained serious stab wounds during a fight at the McDonald’s on East Main Street early Sunday morning, according to police.

Officers were dispatched to the 24-hour fast-food restaurant at 2:55 a.m. Sunday on a report of a fight in progress at the site, where they were told a large group had congregated, Lt. Tom Scanlon said Tuesday.

When officers arrived, they found two men had been injured in the fight, Scanlon said.

A 40-year-old resident of the East Side was rushed to Stamford Hospital with a deep wound to his abdomen that exposed some of his intestines, Scanlon said. Additionally, the man had a stab wound to his upper right chest and one to his rear armpit, Scanlon said.

The man was sent into emergency surgery and was in stable condition Tuesday, Scanlon said. A second man, the stabbing victim’s 23-year-old cousin, sustained some minor injuries, mostly cuts and scrapes, police said.

Witnesses told police investigators that a group of men began arguing with the two men and a fight broke out, which escalated into the stabbing, Scanlon said. The suspects then fled the area, he said.

Investigators were talking to witnesses in hopes of identifying the attackers, Scanlon said. “We haven’t determined what the back story is yet,” he said.
