Officers from the Metropolitan Police Service's Sexual Offences Investigation Unit are appealing for information following a sexual assault in Harrow.
On Monday, 5 August 2013 at about 01:00hrs a 26-year-old woman boarded a route H9 bus at Kenton Station HA3 and alighted at St Leonards Avenue, HA3.
It is believed that the suspect followed the victim off the bus; she was approached from behind, dragged behind some parked vehicles and sexually assaulted.
The victim managed to persuade the suspect to accompany her to her home address nearby, knowing her flatmates would be in and, when she got there, she raised the alarm. A flatmate chased the suspect but he made off.
The suspect is described as being in his early 20s, of Asian appearance with an English accent, skinny and wearing dark clothing.
Police would like to speak to anyone with any information about this incident.
Officers are also keen to identify and speak to the man pictured in CCTV images released today.
Anyone with information is requested to contact DC Dave Berry or PC Elly Mitchell at Barnet police station on0208 733 5062 (voicemail if out-of-hours) or Crimestoppers anonymously on 0800 555 111.
