MCBD has been handed the five-year contract by the Metropolitan Police's Directorate of Public Affairs (DPA).
The agency will create communications for a range of issues concerning the Met's impact on the safety of Londoners. These include drugs, terrorism, gun crime, hate crime, domestic violence and street crime. The various executions will be united under the 'Working for a safer London' banner.
Recruitment advertising is not included in MCBD's remit; M&C Saatchi will continue to handle national advertising for the UK's police force.
The review began last May, with 50 agencies expressing an interest in the account. This was whittled down to 12, with three chosen for the final pitch in November: MCBD, Barrett Cernis and Rainey Kelly Campbell Roalfe/Y&R.
MCBD takes over from The Advertising Syndicate, which has been the incumbent since February 1997.
The creative appointment does not affect MediaCom's hold on the planning and buying account.
