While former New England Patriots tight end Aaron Hernandez sits in a Boston jail accused of killing Odin Lloyd, he sparked an early Saturday morning brawl at a diner in Hartford, Conn.

In what appears to be a case of mistaken identity, a fight broke out after someone shouted “Hey, Aaron Hernandez” to a man who resembled the former Patriots tight end. That man was believed to be D.J. Hernandez, the disgraced football player’s older brother.

By the time police arrived at the diner, the man thought to be D.J. Hernandez had left. Police say he was not involved in the melee.

Three people were arrested — two of those arrested told police that they indeed had been sitting with D.J. Hernandez.

According to the Hartford Courant, someone in the diner yelled at the person who was shouting Hernandez’s name to shut up, and the fight started. A woman was punched in the face and pushed to the floor. The two men sitting with Hernandez suffered facial cuts.

“It was just a customer who thought it was Aaron Hernandez. That’s how the fight actually started,” an employee of the diner told the Iowa City Press-Citizen. “They thought it was Aaron Hernandez himself.”

D.J. Hernandez is an assistant coach under Kirk Ferentz at Iowa where he coaches tight ends.

He was a two-year captain at the University of Connecticut and also coached at a local high school before moving to Iowa City.
