A mob of up to 100 youths brought a McDonald's to a standstill with a 'shameful' rampage which saw teenagers verbally abuse staff, jump over the counter and steal food.
Youths chanted obscene songs at two female workers at the fast food restaurant in Wigan, Greater Manchester, as they tried to serve customers - and the video of their antics has gone viral after it was uploaded to YouTube.
The yobs vaulted the counter into the kitchen area, threw litter and hurled abuse. Staff were so scared they pressed a panic alarm and police were forced to break up the disorder.

Melee: Police had to break up the disorder after staff pressed the panic alarm
McDonaldís said: 'We were appalled by the deplorable behaviour displayed in our Standishgate restaurant.
'The safety and security of our employees is of paramount importance, and it is completely unacceptable for them to be the targets of any level of intimidation or abuse.
'On the evening in question, employees activated the staff alarm system which is installed to guard their safety and limit the need for confrontation.
'The alarm system alerts the central CCTV control room to any disturbance and gives them full control to monitor the situation.
'Customers in the restaurant at the time the alarm was activated will have been informed over the speakers that they were being recorded and that the police had been called.
'Fortunately, nobody was injured. But we are offering our full support to those staff members affected by the shock of the incident. We are also cooperating fully with the police.'

Sergeant Nicola Williams from Wigan Neighbourhood Policing Team added: 'A large number of teenagers behaved in a wholly unacceptable way, the staff working in McDonalds were subjected to abuse of an indecent nature and were terrified.
'It is not acceptable to behave like this in a family restaurant. We have launched an investigation to identify those responsible and bring them to justice.
'If you were in Wigan on Tuesday night and witnessed the incident or have any information, please contact us.'
Those who viewed the footage condemned the yobs. One said: 'Wow, Iím ashamed of my own home town. And to say I know some people in that video. Good God. Sort yourself out people.'
Another said: 'Wigan is not a wonderful town. It's a sh*thole, believe me.'
Another user praised the staff in the restaurant, and added: 'This is just ridiculous. There is nothing funny about this at all. These people should be ashamed of themselves, but they wonít be.
'I think the staff acted appropriately and I commend them for being as calm as they were, given the situation.'
A fourth said: 'Anyone working there deserves a medal, even if it doesnít require qualifications.'
