Cops' spy fear; britain ROUND-UP.
Members of the Metropolitan Black Police Association said they have been forced to use counter surveillance tactics.
Officers have purchased unregistered pay-as-you-go phones and had their offices swept for bugs to block eavesdropping.
They fear senior Met figures will stop at nothing to undermine their organisation and its key members, amid bitter accusations of racism at the head of Scotland Yard.
One officer said: "There is nothing we would put beyond the Met.
"Nobody can believe how desperate these people are."
