Police in Southwark are appealing for anyone who recognises this man to get in touch following a "disturbing incident" on the Rockingham Estate.
On Thursday 25 June at around 2.15pm the suspect knocked on a door in Whitworth House, Falmouth Road.
When a 41-year-old woman answered the door he asked if her husband was home, before making suggestive comments and grabbing the victim by the wrists. She managed to close the door and the suspect left.
"We are unsure at this stage what the suspect's intentions were, but this was a disturbing incident which has left the victim very shaken," says Detective Constable Colin Dady.
"I would urge anyone who recognises the suspect to contact police."
The suspect is described as a light skinned black man, aged approximately 21-25 years, about 6 ft tall with black hair in plaits. At the time of the incident he was wearing a yellow t-shirt and blue jeans.
