A Swedish football hooligan has revealed how gangs including a 'Neo-Nazi firm' joined together to launch Friday's vicious attack on migrants.

Up to 50 black-clad masked men stormed Stockholm's main train station around 9pm and targeted unaccompanied children who did not look ethnically 'Swedish'.

They handed out leaflets with the slogan 'enough now' emblazoned across them and incited people to attack the migrants before beating several 'foreign' people and fleeing.

A member of one of the city's football 'firms' has now admitted to MailOnline that his group, DFG, was responsible for the attack .

He revealed a handful of men from the club teamed up with others from their usual rivals AIK, as well as being joined by several Polish hooligans.

Speaking on condition of anonymity, he said: 'This is something that we have talked about for a long time.

'We feel the police are not doing their job. Our wives, girlfriends and daughters cannot feel safe in the centre parts of Stockholm during the night.

'We feel that this is shameful for a country like Sweden and wanted to make a statement that it is not OK.'

Members from DFG - or Djurgårdens IF - and AIK are typically rivals and have only joined together once before, the man, who was not part of the attacks, also revealed.

Video footage had emerged showing the mob sprinting through the station as children ran away screaming

Before the attack, a group of people started handing out xenophobic leaflets with the message 'Enough now'

Authorities had said the mob was linked to the Swedish football hooligan scene

They usually clash with each other in relation to sporting events and last fought each other in a bloody six-minute battle following a hockey game just 17 days before Friday's attacks.

The man added: 'The only time that we have seen something like this [Friday night] was in the Euros in 1992, when they [the firms] teamed up to fight English hooligans under the banner "defend Stockholm".'

Friday night's surprise attacks shocked station workers and migrants who had congregated at the station for the evening.

Witnesses reported seeing groups of up to 50 men storming through the station as groups of youths attempted to hide.

Johanna Brixander, who supervises volunteers working to try and prevent crime at the station, said she saw children screaming as they ran down the escalators in a desperate bid to get away from the men.

She said: 'A few seconds later a group of masked men came running towards us. They were screaming chants I have never heard before in Swedish.

'People got beaten really bad before our own eyes. Big groups of youths tried to hide everywhere. It was very chaotic and I was really afraid when it happened.

'Most of the kids who got beaten were just ordinary people born and raised in Sweden,' she added. 'Their hair colour just happened to not be blonde.'

Assam, who was born in Sweden, was pushed to the ground by a masked man but did not get injured. He said the men did not care whether they were attacking boys or girls - their only focus was colour.

'I did [not] really understand what was happening until I was laying on the ground,' Assam said. 'It was totally insane.

'My friend's girlfriend was badly beaten, they kicked her while she was laying on the ground.

'[It] did not make a difference if they were beating girls or boys. Everyone who had dark hair or skin was their targets.'

One gang member was arrested for punching an officer in the face and several others were detained for public order offences - but the majority of the group managed to escape.

Police are currently battling to control the 'firms' with officers claiming the rivalry often affects the entire Swedish capital.

Previous reports also suggest an entire restaurant in Stockholm was destroyed when one of the 'firms' held a Christmas party.

Around 50 men who attended the event started a fight using the restaurant's furniture and glassware before throwing stones at officers when they arrived to calm the situation down.

Fredrik Gårdare, director of the country's special action force against the firms, previously told Aftonbladet: 'If we look at recruitment and those who join these gangs they are all quite young.

'It is, of course, some who are interested in football, but we also see those who are not.'

He added to MailOnline: 'It has become somewhat fashionable for the established criminal environment to look towards [the firms] and examine whether the grass is greener inside [them].

'[The firms have] the same kind of standards and regulations as criminal gangs.

'It is essentially the same quest for communion with family, friends and then to do things together - partying, fighting and... various crimes - that makes them feel like they are in a brotherhood.'

The attacks, however, do not appear to have put everyone off from going out in Stockholm.

Assam said he was not scared enough by Friday's attacks to stop meeting his friends at the station.
