The number of murders involving Asians has risen by 300 per cent in a decade compared to 32 per cent in the general population. Assistant Commissioner Tarique Ghaffur, Britain's most senior Asian police officer, said today that unless action is taken, some communities could become "crime-ridden ghettos". Speaking on BBC Radio's File On 4, Mr Ghaffur also revealed that 20 per cent of the Met's kidnapping cases now involve Asians.
