A man is tonight in a "critical condition" after being hit by a car and getting trapped underneath.
Shocked passersby tried heroically to lift the vehicle off the victim and give him CPR following the collision in Wirral at lunchtime.
He was rushed to hospital by emergency services and is now fighting for his life.
It is understood the man had been cycling when he was struck by a dark coloured Vauxhall Astra, reports the Liverpool Echo.
One witness reported seeing people running to help lift the car, and there are reports the man was given CPR at the scene before an ambulance arrived.
North West Ambulance service confirmed that the man is in a "critical condition" and was rushed to Aintree Hospital.
A spokesperson also said that multiple response vehicles attended the incident along with the air ambulance, which is believed to have landed at a nearby golf course.
Witnesses at the scene described members of the public running over to try and help the cyclist after the incident.
One woman who lives nearby said: "I looked out of my window and saw that somebody had been knocked down at the roundabout and trapped under a car.
"I saw about six people lift the car up and put it on its side to free the man. The air ambulance came and landed on the golf course.
"The paramedics put screens up while they treated him. It looked really serious."
Another member of staff at a cafe close by, who saw the aftermath of the incident, said: "It happened sometime after 1.30pm.
"Customers ran out to help after someone on a bike got hit. I saw a woman performing CPR on the person.”
Another man who was working at a nearby bar described seeing a man "trapped under the car".
He said: "I was serving customers at the time when I saw lots of people crowded round the car on the roundabout.
