A youth was hit by his friend's car after a dangerous game of cat and mouse went wrong.

Sam Marshall from Watford witnessed the incident. She said:

“They were just messing around, the car drove towards him and they must have thought he'd get out of the way but he didn't make it.”

Paramedics were called to the Waterfield's retail park at 8.38pm last night where Patrick, 19, was breathing but not completely alert.

Ms Marshall added: “He went over the bonnet and cracked the windscreen, then he was lying on the floor with blood coming out of his ear.”

The man was taken to Watford General Hospital. More to follow.
