The inquiry, headed by former director of public prosecutions Sir David Calvert-Smith QC, said there was "ice in the heart of the police service" on race issues. Pc David Davies, 29, who was based with the territorial support group at Paddington, was required to resign after being found guilty last July of racially aggravated assault and intending to damage or destroy property during an incident at Piccadilly Circus Tube station. Guildhall magistrates were told how, in June, 2003, he barged into the operations room just after midnight and demanded the station staff call the police.
