An elderly couple were recovering in hospital after being struck by a motorbike in a hit-and-run incident at a small seaside town.
The rider spoke briefly to the female victim as she lay injured on the ground in Frinton-on-Sea, Essex, before he made off in a car that had arrived to collect him.
The couple, who had travelled from Berkshire to visit relatives, were struck from behind when the motorbike went out of control and mounted the pavement.
The man, 64, suffered a fractured skull and three breakages to his left arm, while his wife, 60, had three fractures to her right arm.
They were taken to Colchester General Hospital where their condition was described as stable.
Essex Police launched a search for the rider and issued an appeal for information about the incident which took place on Cliff Way at 8.30pm yesterday.
The motorbike was a red 1100cc Yamaha XVS. The rider, who wore an open-faced crash helmet, left the scene in a silver car.
Sergeant Dave Cook of Essex Police said: "We know that the motorcyclist went to talk to the injured woman while she lay on the ground.
"Her husband was unconscious nearby. He said a few words then callously walked away from the couple and got into a car that came to collect him."
