The Metropolitan Police are investigating allegations of fraud at a defunct charity that supported people with HIV and Aids.
They confirmed they were looking into the finances of the UK Coalition of People Living with HIV and Aids, a London-based charity that closed three years ago because of debt.
A police spokesman said: "We can confirm that an allegation of fraud was made regarding the finances of a charity based in Kensington & Chelsea. Investigations are ongoing and no arrests have yet been made."
Stephen Bitti, former UKC chief executive officer, said he was unaware of the allegations. Third Sector was unable to contact Bernard Forbes, who was chair of the charity when it folded.
A Charity Commission spokeswoman said: "Concerns were raised with the commission regarding the UK Coalition of People Living with HIV and Aids. We considered these concerns and determined there was no regulatory role for the commission."
