A construction worker has been crushed to death while unloading metal beams on a Brentford building.
Felllow employees at the site in Harlequin Avenue were said to be distraught following the tragic accident which claimed the life of east end resident Hughes Makambila.
An air ambulance, two regular ambulances and two fast response cars all rushed to the scene following a 999 call at 11.15am but were unable to save the injured man.
A spokeswoman for the London Ambulance Service said: "Sadly a 35-year-old man was pronounced dead at the scene by a doctor from the air ambulance."
Hounslow police, who are investigating last Thursday's incident alongside the Health and Safety Executive (HSE), believe the man, who was originally from the Ivory Coast, was unloading large metal beams from a lorry when one slipped and hit him.
Police have spoken to the driver of the lorry, which was carrying 20 tonnes worth of beams, and to two other men working nearby.
They are keen to hear from any other witnesses or anyone with information about the accident. Call Det Sgt Dave Purvis, of Hounslow CID, on 020 8247 6160 or Crimestoppers anonymously on 0800 555 111.
