A teenager walking his dog was approached and robbed by a group of about 15 men.
The men, who were described as both white and Asian, tried to assault the victim and then made off with his dog.
The robbery took place just off Bradbury Street, in Ravensthorpe. The dog, an Irish staffy, has since been recovered. Officers from West Yorkshire Police have arrested a man in connection with the incident. Anyone with information can contact Kirklees CID on 101.
