An 18-year-old man is in a critical but stable condition in hospital after he was crushed under a lorry on Baker Street last week

The teenager suffered serious leg and pelvic injuries as the vehicle trapped him from the waist down just before 1pm last Thursday.

He underwent emergency surgery that afternoon but has since remained in a critical condition.

Police believe the lorry, an HGV tipper, was reversing at the time of the incident and a 42-year-old man was arrested at the scene on suspicion of dangerous driving. He has been bailed until January.

Witness Dalil Chaikh was one of the first on the scene and attempted to comfort the victim as he lay trapped under the vehicle.

He said: “He was screaming so much. I kept saying to him that it was going to be OK and the ambulance was on its way.

“He just kept on asking for help and screaming so loud.”

Another witness who worked in a cafe next to the accident said: “I heard the most terrible screams from the man who was trapped.

“People went over to try to help him but he was stuck so they had to call an ambulance.”

Police, the fire brigade and paramedics all attended the scene to try to remove the man who was trapped under the back wheels of the truck.

A London Ambulance Service spokesman confirmed they had paramedics on the scene within two and a half minutes before they took the victim to St Mary’s Hospital. Baker Street remained cordoned off to traffic and pedestrians for much of the afternoon.

The incident follows the death of 97-year-old Nora Gutmann who died in June after being in a collision with a lorry just 150 metres away on Marylebone Road.

Ms Gutmann was crossing the busy road at a pedestrian crossing when the accident occurred.
