Police in Chicago arrested more than 100 people on Sunday and Monday following a police shooting and subsequent looting, according to NBC News. 

Mayor Lori Lightfoot and Police Superintendent David Brown held a press conference Monday morning to explain what happened, telling reporters that hundreds of people began looting stores in the city because of a misunderstanding about an earlier incident involving a 20-year-old who was shot by police, reports ABC 7. 

Lightfoot and Brown explained that on Sunday, someone called the police in Englewood about a man with a gun. When police arrived, the man began to shoot at the officers, ABC 7 reported. The officers returned fire and struck the 20-year-old. According to Brown, the young man is in stable condition at the University of Chicago Hospital.

Brown went on to explain that police began to see misinformation online that he believes stoked anger and led to the looting.

Photos from the scene of the initial shooting show people lined up in front of dozens of police officers, who eventually left the area after demands from local residents.
