Luis Cotto, 24, was sentenced Feb. 11 to four years in prison for beating and stabbing a Cook County prosecutor who had attempted to help a gay couple that Cotto and a friend were harassing, Chicago Tribune reported.

The incident occurred Sept. 14, 2012, on the 200 block of West Diversey Parkway. The prosecutor, who has since left the state’s attorney’s office, saw Cotto and his co-defendant, Edgar Diaz, approach the couple and punch one of them.

They began chasing after the prosecutor after he told them to stop. He fell, at which point Cotto and Diaz attacked him, including breaking a beer bottle across his back and stabbing him with it. The prosecutor required 40 stitches.

Cotto had previously pled guilty to aggravated battery; Skokie Branch Judge William O’Brien handed down his sentence. Diaz is currently awaiting trial.
