The unnamed prosecutor, on his way to meet a friend for fishing on Chicago's lakefront Sept. 14, ordered the two men to stop shouting at the couple, Sally Daly, a spokesman for the state's Attorney General's Office said, adding, "They turned on him and ran at him."
The prosecutor was cut near the left eye, on his side and under his right arm after being struck with a beer bottle, and walked to a local hospital after he met his fishing colleague, the Chicago Tribune reported Monday.
He was later transported to Advocate Illinois Masonic Medical Center with what police described were "non-life threatening injuries," the Chicago Sun-Times said.
Edgar Diaz, 21, of Chicago was charged with attempted first-degree murder and aggravated battery, police said.
