Some Teds formed gangs and gained notoriety following violent clashes with rival youth gangs as well as unprovoked attacks on immigrants. The most notable clashes were the 1958 Notting Hill race riots, in which Teddy Boys were present in large numbers and were implicated in attacks on the West Indian community. According to reports released decades after the riots, "Teddy boys armed with iron bars, butcher's knives and weighted leather belts" participated in mobs "300- to 400-strong" that targeted Black residents, in one night alone leaving "five black men lying unconscious on the pavements of Notting Hill."
