A girl's 18th birthday party turned into a major "riot" after an invitation was posted on social internet networking site Facebook.

Gangs of teenagers tried to gatecrash the fancy dress bash after a friend of the unnamed youngster put a message about it on the internet.

Police had to be called to the party at a function room at Flixton Football Club when fighting broke out as guests tried to eject the invaders.

Scuffles broke out in and outside the club and the bar was closed early as officers arrested four teenagers including guests dressed as cartoon characters from the Incredibles.

Details of what police described as a "large scale brawl" emerged as guest Frankie Furnley, 18, dressed as Mr Incredible, was convicted of assaulting two police officers and a public order matter.

Furnley, of Aldworth Grove, Sale had been invited to the party and had gone outside when the disturbance broke out, magistrates at Trafford were told.

Prosecuting Miss Sheryl Mottram said: "On the 8th of March this year officers were called to Flixton Football club's car park area. When they arrived there was a large number of people and some kind of disturbance.

"As one PC was trying to find out what was happening he noticed Mr Furnley who was outside."

Miss Mottram added that Furnley then became aggresive and started swearing at the officer.

She said: "The officer warned him about his behaviour but he continued to be abusive and so was arrested for a public order offence.

"As he was being arrested he then began to struggle and two other officers came over to assist. The defendant kicked out and hit the right hand of a PC Gatric. He then bit the hand of Pc Parkin.

"Fortunately the officer was wearing gloves at the time and his skin wasn't broken. Furnley was arrested and interviewed and he said that he had been out at the fancy dress party that evening and had been drinking.

"He said that he had seen a disturbance outside but said he didn't think he had done anything to warrant his arrest at the time."

Defending Mr John Mail said Furnley was originally bailed for these proceedings but had been in custody since May 9 after he breached a curfew order.

He said: "It is a very unsavoury incident and this sort of behaviour is totally unacceptable. He had had a chance to reflect on his behaviour in custody.

"He was at an 18th birhday party and he says a number of people were outside and they ran off before the officer took hold of him.

"The officers were far bigger than him and he did receive injuries as a result of his struggle.

"This is the first time he has been in custody and he has now spent a month and a week in custody. He has written a letter and a poem which gives an indication as to what sort of person he is.

"He has recently lost two friends and an Auntie. He is hopeful of completing a hair dressing course in September and he has been made fun of because he wants to be a hairdresser.

"The last month has been difficult for him."

Furnley was given a 6 week curfew order to stay at home between the hours of 8pm and 7am. He was also ordered to pay £25 compensation to each of the police officers.

Sentencing district judge Mr Alan Berg said: "The reality was you were drunk and you behaved in a most unpleasant and unacceptable way.

"The police officers have a duty to maintain law and order and the peace and when idiots like you come in and intervene in something that was nothing to do with you you can expect to be arrested.

"You really ought to be ashamed of yourself. You are a young man with a talent and there are two paths you can go down and if you go down the wrong path you will spend a lot of your life behind bars."

At the time of the incident eye witness James Taylor, 60, said: "It really kicked off, it was like a riot, it was very frightening but the police came and did a marvellous job."

He said the trouble continued the next morning as youths set fire to a number of pallets around the back of the club, and as a safety precaution the club called the fire brigade.

Club chairman Phil Greenhalgh said: "We had an 18th birthday party, which was a fully ticketed event and fully licensed, but a friend of the birthday girl put it on Facebook.

"The police were called, the bar was closed and it was all sorted out.

"It was bad for the club because we lost money as we had to close the bar early, but it was a one off, in the past 12 months the police have only been called out twice.

"We are a responsible club but these things do happen. The problems are caused by 18 and 19 year olds."

An 18-year-old from Bolton was fined for a public order offence at an earlier hearing whilst two other teenagers, aged 18 and 17-year-old, were given fixed penalty notices for public disorder.
