Police have confirmed that no arrests have been made in the investigation into the death of TV presenter Peaches Geldof, as her family mark the one year anniversary since her passing.

The 25-year-old daughter of Sir Bob Geldof died of an accidental heroin overdose on 7 April, 2014 at her Wrotham home, but Kent police are no closer to identifying the dealer who sold the journalist the fatal drugs.

A spokesman for the force said in a statement released to Mirror Celeb: "The investigation remains live and officers are keeping the family updated as it continues. No arrests have been made."

The publication claims they contacted Kent police every week for eight months to obtain information about their investigation, but had not received a response until the statement was released.

Detective Superintendent Paul Fotheringham is still said to be leading the investigation and remains committed to the case.

A memorial service to make the year anniversary is expected to be held by Geldof's family and her younger sister Pixie Geldof, 24, is said to have created a memory box for her nephews.

A source reportedly told Closer magazine: "She wants everyone to light a candle and pick a song that reminds them of Peaches."

Geldof was found in a spare bedroom of the property by her husband, Tom Cohen. She is survived by her two sons, Astala, two, and 23-month-old Phaedra.

An inquest which concluded in July 2014 found that Geldof's overdose was 10 times bigger than the one that killed her mother Paula Yates in 2000.

Cohen and his father-in-law Bob are said to be working on launching a charity to help drug addicts in Geldof's honour.

An insider said of their friendship: "Tom and Bob have really bonded over the last year and have a great relationship. They are looking at setting up a charitable foundation in Peaches' name to help young people battling drug problems."
