Thames Valley Police is appealing for information after a 15-year-old boy was robbed in Milton Keynes on Friday.
The boy was walking along Lloyds at about 12.30pm and was near to the junction with Button Grove, when he was approached by three men.
One of the men stood in front of him while the other two remained behind him, and told him that he had seen him withdraw money from a cashpoint and to hand it over. The boy refused to hand over the money and he was headbutted by the man, causing him to fall to the floor. He then got to his feet and handed over £20 and the three men walked off in the direction of Milton Keynes College.
The first man that headbutted the boy is described as white, 17 to 18-years-old, between 5ft 9ins and 6ft, of a medium build, a small goatee beard, with gaps between his teeth and acne. He was wearing a dark green hooded top with the hood pulled up.
The other men are described as both being white, 17 to 18-years-old, between 5ft 9ins and 6ft, and of a medium build.
One of them was clean shaven with a scar to the left side of his face near to his eye and was wearing a white hooded top with the hood pulled up.
The other man was also wearing a hooded top with the hood up, but the colour is unknown.
Det Con Reg Jones said: “The boy was not badly injured in the robbery, but has been left shaken by what happened.
“I am keen to speak to anyone who was in the area at the time who may have seen this incident, or saw these men either before or after the robbery happened.”
