From time to time I read 'Hungary Today' an English Language online news site which I'm convinced is Government run.
Here's an extract from it's match report.
"As a matter of fact, the match wasn’t free of minor disruptions either. First, some English fans booed the Hungarian national anthem, while the few Hungarians present did so with kneeling English players. Then, in the opening minutes of the game, one Hungarian fan reportedly made racist insults towards one of the stewards. In response, police officers went to the sector to arrest the misbehaving fan. However, other fans did not let them through and clashed with the policemen. After a short fight, with some Polish fans also joining in (who arrived to support Hungary), police were apparently forced to leave the sector but the troublemaker was taken into custody."
