Police hunt boy sex attacker

Police are hunting a boy thought to be as young as 15 who indecently assaulted a teenage girl.

The 17-year-old girl was walking through a park when the boy rode up to her on a mountain bike and tripped her up before pinning her to the ground and kissing her.

She screamed and tried to hit him before he got back on the bike and cycled off.

Detectives urgently want to speak to anyone who saw the attack on Evans Lane in Kidlington, Oxfordshire, on Saturday at about 1800 GMT.

The attacker is described as black, 5ft tall, 15-18 years old, clean shaven and of slim build.

He fled the scene in the direction of Croft Avenue.
