It's a bit odd if true, but the "weapons" that the team buses are allegedly taking in to the stadium for the hooligans are "flares and smoke bombs".
I think it might be a little misleading by the article talking about stabbings and a slow criminal justice system, then going straight into the next paragraph about the club smuggling in smoke bombs.
It sounds a bit like the way the HDM go on about crowd violence by City fans after a flare goes off in the away end at the MKM.
Not sure about weapons but in the Balkans football clubs are linked with political parties, their supporter groups head honchos often providing security for politicians. In return supporter groups get paid travel, beer and food money. I presume a similar situation exists in other eastern European countries.
Have mentioned on here before about OFK Belgrade who played Hull City. OFF owned now by the singer Ceca who was married to the dodgy character Arcan until he was assinated.
