A security guard was left with a fractured knee during a struggle to restrain a drunk hotel guest.
Usually law-abiding dance teacher, Liam Raydon, flew off the handle during a row with his partner outside the Travelodge on Newcastle Quayside.
Due to him screaming and shouting, staff decided to stop him going inside in case his behaviour alarmed other guests.

He responded by running towards the entrance, punching a receptionist and was then tackled by security.
As one guard tried to restrain him on the ground, his 61-year-old colleague fell to the floor for reasons which are not clear and suffered a horrific injury to his knee.
As Raydon was given a suspended prison sentence, Newcastle Crown Court heard the injury has had devastating consequences for the victim.
The offences happened on June 1 last, when Raydon and his partner were staying at the hotel.
After becoming aware of the row, the two security guards went outside to try to calm matters down but Raydon continued shouting and screaming.
They decided to stop him going back inside and told a man working on reception, who had come outside, to secure the door.
Prosecutor Rachel Glover said: "The defendant ran towards him and punched him in the face.
"The defendant then made his way inside and went towards the lifts and at this point he was followed by both security guards who tried to restrain him
"There was a struggle and (the 61-year-old) fell to the ground and sustained a knee injury and as a result he was unable to get up."
At hospital, it was discovered the guard had a fractured knee. He was advised to have surgery but declined as he fears anaesthetics.
He was left needing to rest for a considerable time and had to wear a leg brace and use crutches and a walking frame while living downstairs and having adjustments made to his house.
He said that for a time "the most simple tasks are now almost impossible".
The victim added that he has been unable to work, causing financial stress for him and his wife and he fears losing his job due to his injury, which continues to affect him.
The receptionist who was punched said he was left feeling "annoyed and frustrated", adding: "I don't expect to come to work and be assaulted."
Raydon, 26, of Parmontley Street, Scotswood, Newcastle, who has no previous convictions, pleaded guilty to GBH and common assault.
He was sentenced to six months suspended for 18 months with 200 hours unpaid work.
Miss Recorder Davies said: "This was extraordinarily unfortunate because he was not the man grappling with you."
Vic Laffey, defending, said Raydon has little recollection of the incident due to the amount of alcohol he had consumed.
He added: "He's genuinely embarrassed, remorseful, ashamed and concerned about the condition of the two men he harmed, particularly the one he harmed severely.
"He had an argument with his partner, who is the young man at the back of the public gallery and his parents are here too.
"He acted completely out of character on one night."
Mr Laffey said the 61-year-old victim hardly got a chance to intervene before he somehow suffered the injury to his knee.
He added that Raydon had to resign from his job in the last few days and has been unable to teach children dance as a result of publicity his case received previously.
