THREE thugs attacked a man with learning difficulties and stamped on his head during a robbery bid.
Police described the violence as needless and have appealed for people who saw the three attackers to contact them.
The 37-year-old victim from Paddock was walking through Greenhead Park on his way to Huddersfield town centre when he was stopped by the three men close to the bandstand at 6pm yesterday.
One pushed into him and made him lose his balance while another hit him around the head until his glasses fell off.
The victim fell to the ground and the third attacker then stamped on his head.
The thieves then demanded money. When he said he had none they ran off.
The victim was shocked and suffered grazes to his head.
Pc Dave McSween- ey, of Huddersfield police, said: "This was a needless use of violence on a vulnerable victim.
"Someone may have seen these three hanging around the park and know who they are."
All are African- Caribbean men who wore dark hooded tops. Two had the hoods pulled up and the other wore his down.
