Police are racing to trace Good Samaritans who helped a man mowed down by a suspected drunk driver - after the victim tested positive for coronavirus.

The man was seriously injured after being hit by a car outside a Radisson Blu hotel in Birmingham at 3.40am today.

The man was rushed to hospital with a serious head injury and a routine test confirmed he had coronavirus.

A woman who was known to the man suffered a leg injury in the collision and it is unknown if she also has the virus.

Police were seen washing the road following the smash

West Midlands Police are urgently trying to find the witnesses who helped the man so they can self-isolate.

A spokesperson said: "A police officer who was in close proximity of them is now self-isolating in accordance with protocols.

"We urgently need the members of the public who were in contact with the man and woman after the collision at around 3.40am to identify themselves.

A car's windscreen was smashed in the impact

"They are not only witnesses, but importantly need to follow Government guidelines when in close contact with confirmed Covid-19 cases.2

Officers were also pictured using a kettle of boiling hot water to wash any infected blood off the road.

One witness said: "At first it looked like a routine crash but a few hours later officers arrived back appearing to look for any trace of blood on the road.

"It was strange to see them washing the road with boiling hot water but they must have been concerned about the victim's infected blood getting onto the tyres of other cars."

An 18-year-old man arrested on suspicion of dangerous and drink driving remains in police custody for questioning.
