The gang was formed by Belizean American Crips who had moved from South Los Angeles to Belize and then to Harlem, New York.
[1] In 1961, a hurricane prompted the first major wave of immigration from British Honduras to South Los Angeles, which was already home to street gangs like the Crips and the Bloods.
[3] The Rollin' 30s Harlem Crips were established in New York City by Dalmin "Diamond" Mayen, his two brothers and several other associates, who set up a drug enterprise in the blocks surrounding 118th Street and Fifth Avenue after arriving from Belize in the late 1980s or early 1990s.
The investigation culminated on August 29, 2013, when 35 gang members charged with various narcotics and weapons violations were taken into custody in an operation involving over 800 law enforcement officers and agents.
[2] On May 12, 2021, the United States Attorney for the Central District of California announced the arrests of three members of the Rollin' 30s Crips, Malik Lamont Poweel, Khai McGhee, and Marquise Anthony Gardon, in the robbery of a $500,000 Richard Mille watch from a patron of Il Pastaio in Beverly Hills, California.
