THE son of motorsport chief Max Mosley has been found dead after a suspected drug overdose, sources said.

Detectives are now investigating whether Alexander Mosley's death was an accident or suicide.

The 39-year-old restaurateur and economist was found dead at his mews home in Notting Hill, west London.

Sources close to the investigation said Alexander may have been taking recreational drugs at the property, which is in the street that TV host Paula Yates was found dead in 2000.

Former Formula One boss Eddie Jordan - a friend of the family - said he was "devastated" and said Alexander was very close with his father.

Neighbours reported seeing Alexander return home with a friend just an hour before he was declared dead by paramedics.
