Police are hunting for a man who exposed himself to a woman in Streatham’s Sunny Hill Road.
The distressing incident happened at around 10am on Friday, January 18, while the woman was driving her car.
As she pulled into the side of the road to let another car pass, she saw a man walking on the opposite pavement exposing his genitals.
The suspect is described as black, aged 50-60 years, approximately 5 ft 8 inches tall and clean shaven.
He was wearing a navy, long-sleeved top, a beanie hat and had his trousers round his ankles at the time.
The woman drove away and called police who searched the area but were unable to find the suspect.
Anyone with information that could help their investigation should call 101 or, to report anonymously, contact Crimestoppers on 0800 555 111.
