A man attacked a group of friends as they attended a Marsden Jazz Festival – and then knocked a policeman’s tooth out.

Sean Annandale, 20, appeared before Kirklees magistrates yesterday when he pleaded guilty to a string of charges.

Magistrates heard that on October 11, friends Jonathan O’Callaghan, Joseph Kelly and Thomas Adams were at the popular music event.

At 10pm they were walking along Carrs Road when they came across Annandale.

He was shouting loudly and aggressively to himself and because of his behaviour the group decided to walk away from him.

However they spotted Annandale, of Bay Close, Oakes, Huddersfield, again and this time he lashed out towards them.

Vanessa Schofield, prosecuting, said: “He punched Mr Kelly on the head, pushing him to the floor.

“Mr Adams came to his friend’s assistance and Mr Annandale punched him in the face.

“He then punched Mr O’Callaghan in the head and dragged him across the floor by his shirt.”

Police attended and found Annandale in a car nearby.

He appeared to have been drinking and was arrested on suspicion of drink-driving as well as the three assaults.

Annandale – found with some cannabis in his jacket pocket – then failed to provide the required samples of breath at Huddersfield Police Station.

He also attacked detention officer Gregg Whittaker, Ms Schofield said.

She told magistrates: “The officer found his behaviour aggressive and tried to close the cell door on him.

“Annandale lunged towards him, swinging his arm and catching him in the face.

“As a result of that assault Mr Whittaker lost part of his tooth.”

Magistrates adjourned Annandale’s sentencing until January 22 for a full report.

Unconditional bail was granted.
