A suspected stowaway who is believed to have fallen from the landing gear of a flight into Heathrow Airport has been found dead in a London garden.
The body - believed to be that of a man - was found in Offerton Road, Clapham just before 15:40 BST on Sunday.
Police said it was thought the individual fell from a Kenya Airways flight from Nairobi.
A neighbour said the body fell a metre away from a resident who had been sunbathing in the garden.
The man, who did not want to be named, said he heard a "whomp" so he looked out of an upstairs window and saw the body and "blood all over the walls of the garden".
"So I went outside, and it was just then the neighbour came out and he was very shaken," he said.
The neighbour, who asked not to be named, said a plane spotter, who had been following the flight on an plane tracking app from Clapham Common, had seen the body fall.
The plane spotter had arrived almost at the same time as the police and told them the body had fallen from a Kenyan Airways flight.
"If it had been two seconds later, he would have landed on the common where there were hundreds of people - my kids were in the garden 15 minutes before [he fell]", the neighbour added.
"I spoke to Heathrow. They said this happens once every five years."
Describing the victim, he said: "One of the reasons his body was so intact was because his body was an ice block."
At the scene

Offerton Road in Clapham, on a bright summer's day, is a tranquil and leafy corner of south-west London.
You could be forgiven for thinking nothing of any significance had happened here recently.
Other than journalists arriving, there is little activity, with many people presumably out at work.
But every 30 seconds or so the quiet is punctured by the din of jet engines travelling overhead, indicating the road's position directly underneath a major highway for aircraft, heading for Heathrow from across the globe.
The Met Police said a post-mortem examination would be carried out in due course and the death was not being treated as suspicious.
Kenya Airways said the aircraft was inspected and no damage was reported.
A bag, water and some food were found in the landing gear compartment on the aircraft when it landed.
Security concerns at Nairobi airport
By BBC Reality Check
The discovery of the stowaway who started his journey from the Jomo Kenyatta International Airport in Nairobi has raised questions about the effectiveness of security checks in place there.
The airport is already under a state of heightened security largely responding to the threat posed by the militant group al-Shabab, based in neighbouring Somalia.
A similar incident took place in 1997 when the body of a young man was found hanging in the nose-wheel bay of a British Airways flight from Nairobi after it landed at Gatwick Airport.
The Kenya Airports Authority (KAA) says a team has been assembled to investigate how the stowaway got on board the plane.
The KAA carries out security drills at the airport - most recently in November 2018.
A spokesman for Kenya Airways said: "The 6,840km (4,250-mile) flight takes eight hours and 50 minutes. It is unfortunate that a person has lost his life by stowing aboard one of our aircraft and we express our condolences.
"Kenya Airways is working closely with the relevant authorities in Nairobi and London as they fully investigate this case."
It is not the first death of this kind on the Heathrow flight path.
In June 2015, one man was found dead on the roof of notonthehighstreet.com's headquarters in Richmond, west London, while another was found in a critical condition after they both clung on to a British Airways flight from Johannesburg.
In August 2012, a man's body was found in the undercarriage bay of a plane at Heathrow after a flight from Cape Town.
