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 Arsenal's mobs, tell their stories for the first time.
