LONDON (AFP) - The second most senior Muslim policeman in Britain has been suspended, officials said Friday, days after the country's top Muslim officer was forced to take leave after alleging racism by bosses. The move against Commander Ali Dizaei, which comes in the wake of Assistant Commissioner Tarique Ghaffur's suspension, prompted claims that London's Metropolitan Police has a problem in handling ethnic minority officers. Dizaei, who is president of the National Black Police Association and seen as close to Ghaffur, is reportedly alleged to have advised defence lawyers on how to undermine a prosecution involving the Metropolitan Police. Ghaffur was suspended earlier this month by the force's head Sir Ian Blair after commenting publicly on his race discrimination claim against Blair and other senior officers, prompting an extraordinary public spat. The Metropolitan Police Authority (MPA), which oversees the force's work, said it had decided unanimously to suspend Dizaei, who had spoken to media on behalf of Ghaffur, pending an investigation. "Suspension is not a disciplinary sanction and it is emphasised that suspension should not be taken as a presumption of guilt," it added in a statement. His suspension prompted a "shocked" reaction from Alfred John, chairman of the Metropolitan Black Police Association. "The fact is the two most senior Asian Muslim officers in the country have actually been suspended. There is a problem," he told BBC radio. "The fact is if you are a minority within the Metropolitan Police Service you are treated less favourably." Both the Metropolitan Police and the Metropolitan Police Authority declined to comment on the case or the claims against the force.
