A married dad-of-one has died after colliding with an industrial tipper lorry on his bicycle in Streatham this morning.

The 32-year-old man died in St George's Hospital, Tooting, at 9.42am, about an hour and a half after his pushbike collided with the Cemex vehicle at the junction of Ambleside Avenue and Mitcham Lane.

The victim went into cardiac arrest at the scene and ambulance staff made efforts to resuscitate him there and on the way to hospital.

Sergeant Richard Auty, from Hampton Traffic Garage which is investigating the incident, said a four-axel tipper was travelling up Mitcham Lane and turned left into Ambleside Avenue, where the collision occurred. He said the lorry driver was interviewed at the scene and no arrests have been made.

"This is clearly a tragic collision and we are looking to see if anyone is at fault," he said. "The man's next of kin have been informed and the vehicle has been taken away for forensic mechanical examination."

He added that police are gathering CCTV evidence from the nearby bus junction.

A spokesman from Cemex, a company which supplies cement, ready-mixed concrete and aggregates, said: "At this tragic time we wish to send our deepest condolences to the family of the victim. Cemex has reacted immediately with its own investigation and fully supports the current police investigation into the circumstances."

Charlie Lloyd, a cycling development officer from the London Cycling Campaign, said heavy goods vehicles (HGVs) account for half of the fatalities involving cyclists on London's roads.

"These large four-axel tippers figure most often in this type of accident," he said. "This is an issue for the construction industry - they need to address the safety of their drivers and vehicles.

"We are lobbying the Department of Transport to implement the safer "blind-spot" mirror system on all lorries, which European Union guidelines said should be in place for HGVs built after 2000 by the end of next March."
