Kent Police said it "neither confirmed or denied" a report claiming Peaches Geldof died from a heroin overdose.
The body of the 25-year-old mother-of-two was found at the home she shared with her young family in Wrotham, Kent, on April 7.
The Times (£) claims tests showed Geldof died from a heroin overdose, in a parallel to her mother Paula Yates, who died at her London home in 2000.
An inquest into Geldof's death is set to open later today.
