An officer mans the cordon by The Grove
Police are continuing to investigate the scene of an alleged sexual assault on two women.
This morning officers reduced the cordon to surround just the Harrow School-owned woods at southern fringe of The Grove Open Space in Harrow.
Forensics officers have been scouring the site - which is crossed by at least one public footpath - for clues and the victims are being interviewed.
The Metropolitan Police had no further comment to make on the case when contacted by the Observer.
