In June 2010, through a Freedom of Information Act request, The Sunday Telegraph obtained statistics on accusations of crime broken down by race from the Metropolitan Police Service. The figures showed that the majority of males who were accused of violent crimes in 2009–2010 were black. Of the recorded 18,091 such accusations against males, 54 percent accused of street crimes were black; for robbery, 58 percent; and for gun crimes, 67 percent. Robbery, drug use, and gang violence have been associated with black people since the 1960s. In the 1980s and 1990s, the police associated robbery with black people. In 1995, the Metropolitan Police commissioner Paul Condon said that the majority of robberies in London were committed by black people.
Black males accounted for 29 percent of the male victims of gun crime and 24 percent of the male victims of knife crime.
Operation Trident was set up in March 1998 by the Metropolitan Police to investigate gun crime in London's black community after black-on-black shootings in Lambeth and Brent.
Between April 2005 and January 2006, figures from the Metropolitan Police Service showed that black people accounted for 46 percent of car-crime arrests generated by automatic number plate recognition cameras.
67% of people arrested for gun crime in London are Black, although Blacks are only 12% of the population.
Black men in London are only 12% of the population, but commit 32% of rape.
