Police hunting for a Latvian man suspected of murdering teenager Alice Gross have found a body in dense woodland.
Convicted killer Arnis Zalkalns is the prime suspect in the disappearance of the 14-year-old, who was found dead in the River Brent on Tuesday, following an extensive search.
An area of Boston Manor Park in west London has been cordoned off - a mile from where Alice's body was discovered.
In a statement the Metropolitan Police said: "We can confirm that officers working on the Alice Gross murder investigation, in their continued widening search have today (Saturday) found the body of a man in dense woodland in Boston Manor Park.
"More details will be released as appropriate."
Zalkalns was filmed cycling along the same route behind Alice on the day she failed to return to her home in Hanwell on 28 August.
He was reported as missing just days later.
The 41-year-old worked at a building site in Isleworth, west London, and is thought to have come to the UK in 2007.
Authorities faced criticism for apparently holding no record of his conviction for bludgeoning and stabbing his wife Rudite to death in Latvia.
It also emerged Zalkalns was arrested in London on suspicion of indecent assault on a 14-year-old girl in 2009, but was never charged.
Police had warned he "clearly poses a risk to the public" and urged anyone who saw him not to approach him.
Alice was last seen on CCTV walking along the Grand Union Canal towards Hanwell at 4.26pm on August 28.
Her disappearance sparked a huge police search - the Met's largest since the 7/7 bombings.
Hundreds of officers from several forces around the country were involved in the investigation, while the RAF was also drafted in to help identify new search areas.
She was found dead more than five weeks after disappearing.
Launching a murder hunt, police said "significant efforts" were taken to conceal her body in the water.
A post-mortem examination on the schoolgirl was inconclusive and further tests are to be carried out to find out how she died.
Zalkalns had not accessed his bank account or used his mobile phone since September 3, nor had he returned home to his partner and young child.
He also left behind his passport.
Forensic officers searched his semi-detached house in Ealing, as part of their investigation.
