Troubled rocker Pete Doherty has reportedly turned to Islam after being imprisoned in London's Wormwood Scrubs jail.

Doherty asked for a translation of the Quran and is now 'lapping it up', reports thesun.co.uk.

One of Doherty's friends said: 'He's been reading the Quran since he went into segregation. He's got a lot of Muslim friends and they've been on at him for ages to study it. Now he's on his own and he's got time on his hands to study it.

'I'm surprised how much it has calmed him down as he was very on the edge inside. He definitely seems more chilled. He's lapping it up and really interested in it. I think it's helping him in there.'

Doherty has been having a difficult time since his 14-week sentence began for violating probation by taking drugs.
