Detectives have released CCTV images of a man they want to speak to after a father and son were violently attacked outside McDonald’s in Huddersfield.

The incident occurred at the Gallagher Retail Park in Wakefield Road, Waterloo, at 8pm on Monday.

The victim, a man in his 20s, was in the restaurant with his dad when a group of youths began acting in an anti-social manner.

Staff ejected the group from the restaurant but they remained outside the premises and began making gestures at the father and son.

The victim approached the main suspect in the group outside the front doors to ask him to stop. The father, who is in his 50s, followed his son outside.
