A rapist attacked a lone female on a footpath in broad daylight close to a church and a school while wielding a bottle as a weapon.
The victim, a 30-year-old woman, was sexually assaulted at 12.30pm on Wednesday on the path connecting Roxborough Park with Landsdowne Road in Harrow, close to The Grove Open Space, and the Our Lady and St Thomas of Canterbury Catholic Church and St Anselms Catholic Primary School, both in Roxborough Park.
The news broke on the day police also released two pictures of a man with whom they wish to speak about the rape of a 38-year-old woman in Church Road, Harlesden, on January 15.
Police say the pedestrian was approached by a man who then threatened her with a bottle before raping her.
The suspect is described as black, aged between 27 and 32, and standing around 5ft 9in and 5ft 10ins tall.
He was wearing a dark blue jacket and carrying a bag on his back.
Detectives from the Sexual Offences Exploitation and Child Abuse Command want to speak to anyone who saw or spoke to a man in that location between 11am and 1pm on Wednesday.
Wednesday's attack happened close to where two 14-year-old girls were raped in the woods in The Grove Open Space in 2008.
The culprits, Binak Hasa, then aged 19, and Jeton Jeshari, 18 at the time, lured the pair to the secluded woodland after meeting them on a bus.
Both were convicted of rape at Harrow Crown Court in 2009 and while Hasa was jailed for seven years and eight months, Jeshari received a prison term of seven years and nine months.
There have been no arrests in the investigation into Wednesday's rape.
