In the aftermath of the Heysel tragedy, Margaret Thatcher declared war on the hooligans. It was a watershed moment for English football. Tough new laws were called for - and the incident led to English clubs being banned from Europe for 5 years. But there was more trouble on the horizon. The mobs had found a loophole. Friendlies. And in August 1986, that led to a full blown riot on a ferry in the middle of the North Sea.

Some of those onboard the ferry that night tell their side of the story. When the law caught up with those involved, it came down hard.
