#4 Millwall (Millwall Bushwackers)
The Millwall Bushwackers, who were earlier known as the F Troop, came to prominence in the 1970s and 1980s for their hooliganism. The first instance of trouble came to the fore during a game against Brentford in November 1965 when a grenade was thrown onto the pitch from the Brentford end. While the grenade itself was harmless, the action led to a riot amongst the fans of the clubs involved.
The worst case of hooliganism reported with respect to the club, occurred post the side’s 1-0 loss to Luton Town in 1985 when the Ultras of the club were involved in an altercation that also involved fans from other London clubs such as Chelsea and West Ham. The Kenilworth Road Riot led to the arrest of at least 31 fans on account of violence.
However, the event was the mere beginning of what was to come and shake up the foundations of English football. What followed was a series of riots, physical battles with the opposition fans and numerous bans being imposed on the club by the Football Association and the club retains the notorious reputation of having one of the most violent fans in the world to date.
