A man was critically injured Sunday evening after he opened fire at a Father's Day celebration in a South Side park.
Around 1,000 people were attending Father's Day picnics at Grand Crossing Park Sunday when gunshots were fired into the air around 6:30 p.m., according to The Chicago Tribune.
The man who fired the gun is said to have been part of the celebrations, police say.
Two officers were in the park when the incident happened and were approached by someone who told them about a person shooting a gun, said Pat Camden, a spokesman for the Chicago Fraternal Order of Police.
Camden said there were police at the park because of a shooting several years ago on Father's Day in the same location.
After the officers were informed of the incident, they spotted a man wearing a white T-shirt and holding a 9mm semi-automatic handgun with an extended clip, Camden said.
When officers told the man to drop his gun, he fired at the police, who responded by shooting at the man and critically injuring him, officials said.
Three officers also sustained minor injuries, but they were not shot, according to officials.
The wounded gunman was taken to Stroger Hospital in critical condition, and the officers were taken to Little Company of Mary Hospital in good-to-fair condition, said Chicago Fire Department Chief Joseph Roccasalva.
Police said that members of the Independent Police Review Authority are investigating, and a gun was recovered at the scene.
