The Violent Crime Crack Unit (VCCU) is a security agency of the government of Uganda established in 2001. Originally a military unit codenamed "Operation Wembley", it was put under police control and renamed, amid charges of human rights abuses.
VCCU has since been renamed to Violent Crimes Crack Unit in 2003 and it now called Rapid Response Unit (RRU) from 2007. It is said that Flying Squad is operated by the same people who were in Operation Wembley.
