A builder has died after being removed unconscious from the basement of a building in west London.
Medics from the London Ambulance Service brought the man onto the street for treatment, but he was pronounced dead at the scene at 4.36pm on Tuesday 25 July.
It is believed the man, who was in his 20s, was part of a team carrying out renovations to a building at Berkeley Gardens in Notting Hill, according to the Evening Standard.
The London Fire Brigade was called to the scene in what a spokesman called a “suspected chemical incident”.
The LFB said: ”Fire crews wearing breathing apparatus brought the man out of the building. He was sadly pronounced dead at the scene.
”Firefighters used detection equipment to carry out sweeps of the building and ventilated the property.”
In a statement, the Metropolitan Police said: “Police were called to Berkeley Gardens, W8 at 16:05hrs on Tuesday 25 July by London Ambulance Service.
