Detectives have arrested six youths, including two boys aged 12 and 13, over the death of an Asian teenager who was beaten to death in a West Yorkshire park, police said today.
Amar Aslam (17) was discovered on Sunday night in Crow Nest Park in Dewsbury.
West Yorkshire Police said he "had been subjected to a sustained and vicious beating" and died from head injuries. They said the motive for the attack was not clear.
