A man is fighting for life in hospital after he was mowed down by a van in a suspected hit-and-run in east London.
A witness described how the victim, a 54-year-old man, was left lying in the street with blood pouring from his head after he was hit by the vehicle as he crossed the road in Bow on Saturday night.
He was struck by a van, which is believed to be a dark coloured Ford Transit, and the driver fled the scene, police said.
Police, paramedics and doctors from London’s Air Ambulance raced to the crash near to Bow Road Tube station at about 9.45pm.
Scotland Yard said the man was rushed to hospital where he remained on Monday in a critical condition.
Witness Hussain Manawer was driving along Bow Road when he saw the crash and stopped to administer first aid to the victim.
In a post on social media, he said it was “heartbreaking” to watch as blood poured from the injured man’s head as they waited for the ambulance to arrive.
“He was hit so hard, his shoes were about 15 meters away from his body. The only thing I knew to do was to pray for him,” Mr Manawer, who stopped at the scene with a friend, wrote.
Detective Sergeant Stephen Pidgeon said: "A man has been left in a critical condition and it is of paramount importance that anyone who witnessed the incident or has any information comes forward.
“We know that at least one passing vehicle witnessed the incident as the occupants of this vehicle stopped at the scene and provided first aid to the victim.
“Given the time of evening and that there is a tube station in close proximity there would have been a number of people who may have seen the lead up to the collision or the incident itself. I would urge anyone with any information no matter how small to get in contact."
