Pete Doherty was reportedly filmed injecting heroin at his Wiltshire home last week just hours after the MTV Europe Music Awards ceremony.

Pete spent six weeks in rehab earlier this autumn to avoid being jailed over a drug possession arrest in May and has claimed to be drug-free since then.

However the video, filmed on a mobile phone, shows the Babyshambles frontman “cooking up” and injecting a substance into his right arm.

A source close to the musician told the Sun: “It’s not the first time he’s injected since he was supposed to have gone clean.”

“He may have got clean through rehab, but as soon as the temptation is put in front of him, he cannot help himself. It’s so sad to see. He’s been given so many chances and so many fresh starts and he just throws them all away.”

Pete’s on-off fiancee Irina Lazareanu spoke out at the weekend about how, despite fleeing London, his former drug dealers still hound him to tempt him back to drugs and Pete himself told the NME recently that he’s finding it hard to stay clean: “It’s hard work. I think I miss it a bit.”

“After years of entrenched drug abuse you have a mourning period. I know it’s a bit sad, but I’m in mourning. I’m in mourning for an armful.”

Last month Pete was given a two-year suspended jail sentence, 18-month supervision order and a 12-month rehabilitation order following his May arrest after the presiding magistrate decided that he had shown sufficient motivation to beat his addiction to avoid an immediate jail term.

Speaking to the music magazine late last week, Pete added that he wasn’t optimistic of staying out of trouble and avoiding jail completely: “It’s quite a lengthy probation requirement and drug-testing order.”

“It might have been better to do a couple of months and have it done with, to be honest. But that’s a bit defeatist - it’s pessimistic.

“I don’t want to go to jail, I’ve had enough of all that. But the chances of me not getting arrested once in the next 18 months are quite slim really.”

On seeing the new video, his spokesperson is quoted as calling Pete “a very foolish boy”.
