A man was shot late Friday night in Lawndale on the West Side.
The 23-year-old said he was on the sidewalk about 11:10 p.m. in the 3900 block of West Grenshaw when someone pulled up in a vehicle and offered him cash to buy drugs, according to Chicago Police.
They started arguing about the authenticity of the money, and the person produced a gun and shot the man in the knee, police said.
He took himself to Mount Sinai, police said.
