Frank Crichlow

Crichlow was one of the Black activists known as the Mangrove Nine, who were charged in 1970 with inciting a riot following a protest against repeated police raids of The Mangrove restaurant. The defendants were all acquitted of the most serious charges and the trial became the first judicial acknowledgement of behaviour (the repeated raids) motivated by racial hatred, rather than legitimate crime control, within the Metropolitan Police.
