Heroin is likely to have contributed to the death of writer, model and TV presenter Peaches Geldof, an inquest has heard.

The 25-year-old was found slumped across a bed in a spare bedroom by her husband Tom Cohen on Monday, April 7.

The musician had arrived at their home in Wrotham, Kent, with his mother, and thought Peaches was asleep.

He found their 11-month-old son Phaedra, who Peaches had been looking after, and called to his mother to ring emergency services.

The inquest in Gravesend, Kent, also heard Peaches' father Sir Bob Geldof formally identified her body.

Detective Chief Inspector Paul Fotheringham said a post-mortem examination was inconclusive, prompting further tests.

But he told the 10-minute hearing: 'Forensic samples have been examined and results concluded there was recent use of heroin and that the levels identified were likely to have played a role in her death.'

He said Mr Cohen, 23, went with his two sons to spend the weekend at his parents' house in south-east London.

'This is a normal occurrence which enables Peaches and Thomas to complete work in their respective careers,' he said.

Peaches spent Saturday afternoon until Sunday morning on her own at home.

'Throughout this period she maintained telephone contact with family and friends, including contact with Thomas'.
