LONDON -- Heroin "likely" played a part in the death of British television personality Peaches Geldof, an inquest heard Thursday.
Toxicology tests revealed that the 25-year-old celebrity had taken the substance before she was found dead at her home in Wrotham, in the southeast English county of Kent, on April 7.
She was the daughter of political activist and musician Bob Geldof. The likely factor of drug use mirrors the death of her mother, Paula Yates, who died of a heroin overdose in 2000 aged 41.
The results were formally announced at an inquest at 2 p.m. (9 a.m. ET) but the role of heroin in her death was reported earlier in the day by London's The Times newspaper.
The inquest was opened after a postmortem examination on April 9 failed to establish why she died.
Detective Chief Inspector Paul Fotheringham told Thursday's inquest that heroin was a likely contributing factor, according to a report by NBC News partner ITV News.
"Recent use of heroin and the levels identified were likely to have played a role in her death," said Fotheringham, of the Kent and Essex Serious Crime Directorate.
The inquest heard Geldof was found on the edge of her bed by her husband, musician Tom Cohen, who called the emergency services. Her youngest child, 11-month-old Phaedra was by her side.
Geldof's career saw her dip into various branches of the media, with stints as a model, TV presenter, and a columnist. She had battles with drugs in the past but friends said she had reformed her life after the birth of her children.
Hours before she died, she posted a picture on Instagram of her as a young girl being held by her mother, Yates, who was also a television personality and columnist.
Yates was found dead in her London flat having overdosed on heroin. Her husband after Bob Geldof was Michael Hutchence, singer in Australian rock group INXS. Hutchence was found hanged in his hotel room in 1997, although Yates refused to accept his death was a suicide.
