His father, Paul Lister Calder, 44, of the same address, was sentenced to 10 months in prison after pleading guilty to affray.
Paul Calder Jnr was charged with two counts of grievous bodily harm with intent, one of causing actual bodily harm, a charge of common assault, a charge of assaulting a police officer and one charge of affray.

Newcastle Crown Court heard police found themselves outnumbered after being called to the disturbance outside the Cashmere nightclub in Golden Square in the early hours of August 5.

By the time the incident ended, PC Graeme Hull and DC Keith Turnbull both lay unconscious and seriously injured on the ground after being kicked and punched in the head. The court was told PC Hull is unlikely to return to his police career and DC Turnbull spent six and a half weeks recovering from his injuries before returning to work.

Two other men have been given prison sentences following the incident, Andrew Craig Baxter, 40, of Highcliffe, was jailed for 16 months after admitting affray and assault and Alan Craig, 32, of Grantshouse, Berwickshire, was cleared of affray but jailed for six months after being found guilty of escape from police custody. Mr Craig is lodging an appeal against the sentence.

His wife, Erin Craig, 21, was given a three month suspended sentence with 12 months supervision after being found guilty of aiding and abetting her husband's escape from a police van.

Berwick Neighbourhood Inspector Sharon Stavers: "We are pleased that the judge has passed these custodial sentences. I must stress that this
incident was totally of character for Berwick, where disorder like this is extremely uncommon. The area has a rightful reputation as a very safe place which makes the events of last August stand out.

"Attacks against police officers are totally unacceptable and there is no doubt that without the assistance of the doorstaff at Cashmere the outcome could have been even more serious.

"However these were officers simply doing their job and trying to break-up a disturbance when they were viciously attacked. One even continued to be assaulted as he lay unconscious. One of the injured officers has returned to work but is still receiving treatment for their injuries while another has not yet come back.

"It's essential that those who protect and serve the public receive protection and assurance when performing their duties. We hope these sentences will serve as a warning to others that assaults on police officers will lead to severe punishments from the courts."
