The youth, who can not be named for legal reasons, left PC Michael Donkin and PC Paul Sykes with injuries including bruising and a torn chest muscle.

He pleaded guilty to two accounts of assaulting a constable in the execution of his/her duty.
On the night in question, Alnwick magistrates heard how the officers had attended an Alnwick property to find the house in, what James Long, prosecuting, described as being in an "untidy state."

Police had attended the scene after a call that a female had cut her wrists. The court heard how police had asked the youth to leave to prevent a further breach of the peace, but he refused.

When one of the officers took hold of the teenager's arm, Mr Long described how he hit out at police.

He said he punched and kicked PC Sykes and hit PC Donkin. As a struggle ensued, the youth pulled PC Donkin's fleece over his head.

Officers reacted by using two short bursts of CS gas to calm the teenager down.

But the youth managed to get to his feet before officers over-powered him. He was taken to Bedlington Police Station.

Mr Long said that the ordeal had left PC Donkin with tenderness to his head, a grazed shin and a torn chest muscle while PC Sykes was left with bruising.

But Michelle Lamond, defending, said that the defendant has been left "completely unnerved" by the earlier self-harming incident and questioned whether the police had acted lawfully in trying to remove the youth from the property.

She said: "Police asked him to leave to prevent further breach of the peace. But was there an initial breach of the peace? If there was not then the actions of the police were not lawful. They ask him to leave and he says that he is not leaving. They then place their hands on him and take hold of him and then they start to struggle."

She added: "He accepts there was a struggle during which time he was punching and kicking and he was being punched and kicked."

The youth was ordered to pay £150 to each officer and a six-month referral order was placed on him.
