With the police under pressure to get a grip on the hooligan epidemic, an ambitious young copper comes up with a plan. To infiltrate the firms and go undercover. Covert police operations in London, Birmingham, Manchester and Leeds soon get underway. Michael Layton is a former detective with West Midlands Police. In the mid-80s, he set up an undercover unit which infiltrated the Zulu Warriors, a firm who followed Birmingham City FC. Michael describes how Operation Red Card gathered evidence against the top targets, the danger his undercover officers faced and the constant threat of exposure and reprisals.

For the coppers recruited, it was a terrifying, head-ache inducing, chain-smoking and dangerous life. Two of the officers who risked their lives and infiltrated the Zulu Warriors and another who worked among Arsenals mobs, tell their stories for the first time.

With firms doing battle up and down the country, it was only a matter of time before innocent people got hurt. Even some players were attacked as the hooligans went looking for their weekly adrenaline rush. Ordinary football fans were also caught up in the violence. Darts, bottles, fireworks, even sharpened coins would be thrown on the terraces.

This episode also hears from the families of those who died at the hands of thugs. 21 year old Wolves fan Gerald Comerford went to watch his team and never came home. His family describe the devastation of losing their brother. Tony Bellew also hears about the racism that was rife on the terraces. Black players were regularly subjected to vile, racist abuse, often coming from their own fans. Former Chelsea player, Paul Canoville describes the abuse he endured during his early career.

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.

1985 saw some of the biggest and bloodiest hooligan riots in British football history. In March, Luton hosted Millwall in an FA Cup tie. Millwall’s notorious mobs rioted before, during and after the game. The Kenilworth Road ground was ripped to pieces, and the town was trashed. Police officer Andy Clarke was left fearing for his life as pieces of concrete and plastic seats were used as missiles.

Just two months later, Leeds and Birmingham’s mobs clashed at St Andrews. Hundreds were injured, and a 15-year-old football fan later lost his life.

But then came one of the darkest nights in football history. On 29 May 1985, 39 people were killed at the Heysel Stadium in Brussels during the European Cup final between Liverpool and Juventus. The tragedy led to English clubs being banned from European football for five years.

What turns a fan into a fighter? When faced with a choice, do you turn and run, or stand and fight?

We meet the men who found themselves drawn into a world of running battles and riots during the 1970s and 80s. For some, joining a firm and fighting gave them a new identity. For others, it was the first time they truly felt they belonged.

From a young age, Bill Gardner, also known as Mr West Ham, found a home and a family he never had on the terraces of Upton Park, one he would fight for. For adopted Brummie Cockney Al, the early firms in Birmingham took him under their wing, but it was not long before he was up to his neck in it. In Manchester, a childhood plagued by bullying and racism led Fireman Sam to become part of United's hooligan mob, and for Chelsea fan Mark Alleway, being a football hooligan became an addiction.

But not everyone was signing up. Most fans just wanted to go to the game in peace, but trouble was never far away. Football writer Amy Lawrence and DJ Trevor Nelson recall how getting out unscathed on matchdays was not always easy.

The police and politicians soon realised they had a serious problem on their hands. But despite their best efforts, the mobs ruled the terraces. And for a while, it was chaos.

Former boxing champion and proud Evertonian Tony Bellew delves into the brutal world of football hooliganism. At its height in the 1970s and 1980s, it was labelled ‘the English Disease,’ a time when violence on the terraces was as much a part of the game as a half-time Bovril. Bellew hears from those who lived for the trouble, the men and women whose Saturdays weren’t complete without a brutal punch-up.

He speaks to the innocent victims caught up in the mayhem, the families of those who lost their lives at the hands of thugs, and the undercover police officers who risked everything to infiltrate some of England’s most notorious firms.

He also explores how government crackdowns, tougher laws, and the introduction of all-seater stadiums helped bring an end to widespread hooliganism.
