Claude Massop (12 May 1947 – 4 February 1979) was the leader and strongman of the Phoenix Gang, later renamed the Shower Posse, belonging to Tivoli Gardens, Wellington Street, Rema, Denham Town and the surrounding areas of West Kingston, Jamaica.
By the time he was 18 (1965) he was already the acknowledged leader of what would later become known as the infamous Shower Posse, a gang that was later headed by the notorious Lester Lloyd "Jim Brown" Coke.
By 1967, Massop's main gang rivals were George "Feathermop" Spence, Winston "Burry Boy" Blake and Anthony (Tony) Welch from the nearby area of Arnett Gardens (Jungle).
The gang included at least thirty men at this time and terrorised victims in Tivoli Gardens, Rema and surrounding areas.
Massop died on 4 February 1979 after being shot by police (at least 40 times, according to newspaper reports[4]) along with two other men named Lloyd Frazer and Alphonson Trevor Tinson, following a police car chase after leaving a football match in Spanish Town involving the Tivoli Gardens Football Club.
