Three people were shot at a Taco Burrito King restaurant in Greektown early Saturday after a large group of people got into a physical fight, according to police and witnesses.

Chicago police officers responded to the 800 block of West Jackson Boulevard just after 4:20 a.m., police said. The offender was among those shot, police said.

A 31-year-old man was wounded in the chest and was taken to Stroger Hospital in serious condition, police said. A 26-year-old woman was grazed in the right foot and refused treatment on scene.

The offender, a 26-year-old man, was shot in the left leg and was taken to Stroger Hospital, where his condition was stabilized. Paramedics could be seen wheeling him on a stretcher and into an ambulance while he was locked in handcuffs

Restaurant worker Eric Rosado, 32, said the group was fighting for about 10 minutes before shots rang out. A security guard called police and hit their emergency button before officers arrived.

"It was a tussle for a while. They were fighting for a long time," said Rosado, who was serving food at the time.

The three wounded in Greektown were among 14 people shot between Friday afternoon and Saturday morning, according to police. A teenager shot on Thursday was treated for his wounds when he also sought care at a hospital Friday.
