Yvette Cooper, shadow home secretary and minister for women & equalities, said:
These allegations must be taken extremely seriously by the Metropolitan Police Service, the Crown Prosecution Service and the IPCC.
The police must ensure there is zero tolerance of racism in their ranks, and must act fast to deal with any suggestion of racism that arises. It is vital for justice that everyone from every community can be confident in the impartiality of the police and their ability to enforce the law fairly.
The MPS worked hard to change after the Macpherson inquiry, but the number of these claims now is a very serious concern.
