A cyclist remains in hospital with serious head injuries after he was assaulted in an alleged road rage incident.

The man, in his 60s, reportedly had a fit after the incident in Rochester High Street just after 10am.

Paramedics and the air ambulance were also scrambled and the cyclist was airlifted to King's College Hospital in London where he remains with serious head injuries.

Police have launched an appeal for witnesses to the alleged assault.

A spokesman said: "Officers are investigating following a report of assault where a cyclist was reported to have been assaulted following an altercation with a motorcyclist.

"Officers attended along with the ambulance service and the cyclist, a man in his sixties, was taken by air ambulance to a London hospital with serious head injuries where he remains."

The suspect has been described as a white man wearing a motorcycle helmet. He is of stocky build and was wearing a black bomber jacket, red, white and blue Union Jack shorts and dark trainers.

The man had a female passenger on his black bike - a blonde woman who was wearing a motorcycle helmet, a light grey jacket, white jeans and black boots.

One witness, who did not wish to be named, said a man on a bike jumped a red light and a motorcyclist got off his bike and started hitting him.

The man then fell to the floor and had what appeared to be a fit, the witness said.

A member of the public put him in the recovery position and the motorcyclist drove off, they added.

Other witnesses reported seeing a man being carried into the aircraft on a stretcher.

A baseball cap and a blood-stained item of clothing were left on the pavement as the man was taken away in the helicopter.

An area close to The Crown pub in Rochester High Street was cordoned off by police and a crowd of people watched as the helicopter landed and took off.

The incident did not have anything to do with The Crown.
