Fears that George Michael was killed

Detectives question George Michael's lover Fadi Fawaz as senior detectives take over the inquiry amid fears the singer was killed by a drugs overdose.

Fadi Fawaz, a hairdresser, was questioned by police about pop star's death Michael, 53, died on Christmas Day at home in Goring-on-Thames, Oxfordshire Police officers will report back to the coroner who will eventually hold inquest

The star had a history of abusing drugs and had been gone to rehab at least once George Michael's lover has been questioned by police amid fears he died of a drugs overdose, it was revealed today. The megastar's partner Fadi Fawaz has been interviewed by officers who are also trying to trace everyone who visited his Oxfordshire mansion in the week before he died on Christmas Day. Mr Michael, 53, was found dead in his bed at home in Goring-on-Thames, apparently from heart failure.

Mr Fawaz, who says he was sleeping in his car and later found his body, has now been interviewed by police about what he knows about Michael's final days and hours. Thames Valley Police will speak to relatives, friends and neighbours before they send a report to Oxfordshire's coroner.

A spokesman said: 'This is standard practice in cases such as this to allow the coroner to determine the circumstances of the death'. They denied it has become a Major Crime investigation but senior detectives are involved. A source told MailOnline: 'In a high profile case like this you wouldn't send a Pc to deal with it. It requires a senior detective'. Detectives had asked a paparazzi agency to hand over the pictures it took showing who was coming and going from the star's house before he died. Last week a post-mortem examination proved 'inconclusive' but the results of toxicology tests could shed new light on the star's death, which is currently classed as 'non-suspicious'.

Detectives fear he may have been killed by a drugs overdose. Mr Fawaz, 40, who lives near London's Regent's Park, was questioned this week by police. Police officers are compiling a report for the Oxfordshire coroner, Darren Salter, who will hold an inquest later this year.
