Rock star Pete Doherty walked free from prison today.

The singer, who has fought a long and public battle with drug addiction, served just 29 days of a 14-week sentence for breaching his probation.

He left Wormwood Scrubs Prison in West London at around 7.10am this morning.

Dressed in a suit and tie, he told the waiting media he was pleased to be out and was looking forward to having a rum and coke and spending some time with his pet cats.

He also showed the media a certificate confirming he had passed a drugs test while serving his sentence.

His release comes despite claims Doherty smoked heroin behind bars even though he was taking the heroin substitute methadone.

The Babyshambles singer was jailed last month by District Judge Davinder Lachhar at West London Magistrates' Court.
