Police investigating a rape in Regent's Park have released an e-fit of the person they would like to speak to in connection with the incident.
Officers are appealing to all who recognise the man in the picture to come forward and speak to them.
Detective Inspector Nicky Arrowsmith of the Westminster Sapphire Unit said: "We have had a positive response from park users who were in the area around the time of the incident. However, if you were in the area and have not come forward to speak to our officers, or if you recognize the man in the e-fit, please contact us immediately."
Police launched the investigation after a 19-year-old woman was raped in Regent's Park on Saturday morning, 26th May 2012.
The woman, who was in the south east corner of the park to go for an early morning jog, was approached by a man just before 0700hrs. He dragged her into nearby bushes where she was raped, before the victim managed to make off and alert a passer-by.
The suspect is described as a black man, aged approx 20 of medium build, approx 5ft 7inches tall with short, Afro-style hair. He was wearing a blue or green t-shirt, possible with horizontal stripes, a dark baseball style and dark coloured jeans. He was also wearing white sport shoes or trainers.
The suspect was also described as walking with a distinctive, exaggerated sway from side to side.
DI Nicky Arrowsmith added: "Since the incident additional patrols have been carried out in the park.
"At 06.30hrs a week after the rape took place, Sapphire officers, the local Safer Neighbourhoods Team and Royal Parks Police attended Regent's Park, close to the location of where the rape took place. Officers spoke to members of the public and handed out leaflets in an appeal for information."
Officers will revisit the same area on Saturday, 23rd June to hand out leaflets featuring the e-fit image.
