Doherty held in drugs probe
The Babyshambles star, 31, was one of four people questioned following the death of the 27-year-old filmmaker.
The body of Ms Whitehead, granddaughter of the late Teddy Goldsmith, founder of The Ecologist magazine, was discovered at a flat in Hackney, east London, on January 24 after paramedics answered a 999 call.
She died from a suspected drug overdose.
Doherty was arrested in connection with the inquiry on Friday.
Two other men, aged 41 and 28, were arrested on suspicion of supplying a controlled drug.
