One of the Mayor of London's advisers will not be investigated by the police over claims of fraud because there is "no evidence of criminal activity".
Lee Jasper's role in funding has been called into question
Police were asked to look into allegations made by the Evening Standard about Ken Livingstone's crime and equality adviser, Lee Jasper.
He was later suspended from the Greater London Authority and resigned from the Trident black gun crime advisory board.
But police said no criminal allegations had been reported to them about him.
Mr Jasper has been at the centre of a row over alleged funding irregularities to community projects.
A Metropolitan Police spokesman said: "The Met is investigating six allegations of fraud that have been referred to us in connection with six organisations that received public funding.
"In addition we have received a request asking us to consider the conduct of one individual and his involvement with these organisations.
"To date there have been no criminal allegations reported to us in connection with this individual."
He added: "However matters of alleged misconduct that are not supported by evidence of criminal wrongdoing are not a matter for the police."
A spokesman for the mayor said: "It is quite clear that the charge of 'a tide of corruption' made by London Assembly member Richard Barnes on 13 December is a criminal allegation.
"He should either present evidence to the police for it immediately or formally withdraw it and apologise."
The allegations concern money paid by the London Development Agency (LDA), the mayor's business arm, to a number of black organisations.
One of them was Brixton Base which is run by Errol Walters, a friend and close associate of Mr Jasper.
An internal inquiry had cleared Mr Jasper of any wrongdoing.
