Sean Hoare, the former News of the World showbiz reporter who was the first to allege that then-editor Andy Coulson was aware of phone hacking by his staff, was found dead at his home on Monday, according to a report in the Guardian.

Hoare worked on the Sun and the News of the World with Coulson before being dismissed for alleged drink and drug problems.

Police would not confirm the identity of the man found at Hoare’s address in Watford, north of London.

A police spokesman said, “The death is currently being treated as unexplained, but not thought to be suspicious. Police investigations into this incident are ongoing.”
