A post-mortem examination is due to be held into the death of a builder who was crushed by a collapsing floor while excavating a basement in south-west London.
The 37-year-old man was working on a house in Fulham, on 2 December when the floor fell through.
He was caught under the rubble and died at the scene.
A Metropolitan Police spokesman said the Health and Safety Executive were involved in the investigation.
Basement problems
"We were called at 1500 GMT to a building collapse," he said.
"A man was pronounced dead at the scene."
The man has not been named.
It is the latest in a series of incidents involving London basement conversions, which are carried out to give homeowners more space.
In October a skip in Belgravia sank below the surface of a road after ground was excavated underneath it.
In March, two Camden families had to have their homes demolished after work carried out without planning permission on a nearby property caused structural damage.
