Doherty, 28, has appeared in court on a number of drug offences over the past six months and was praised in April by a judge for "more than co-operating" in his struggle to beat his addiction to hard substances.

The comments were made by District Judge Jane McIvor when the Babyshambles frontman appeared at Thames Magistrates’ Court in east London for a review of a drug treatment order.

The singer told the court: "The people I’m closest to have had enough. They’ve said it’s drugs or them."

A Scotland Yard spokesman said: "About 10pm on (Saturday) police stopped a vehicle in Kensington High Street.

"The 28-year-old male driver was arrested on suspicion of possession of a class A drug.

"He was taken to a West London police station and subsequently bailed to return on a date in June."

Court praises Pete over drugs order - April 18 2007
Pete Doherty is "more than co-operating" in his struggle to beat his addiction to drugs, a judge said today.

Appearing at Thames Magistrates’ Court for a review of a drug treatment order, Pete said: "I’m quite keen to show a negative test as soon as possible really."

Although he arrived 30 minutes late, District Judge Jane McIvor told the Babyshambles frontman: "There’s no obligation for you to turn up to the reviews. The fact you’ve turned up shows co-operation - more than co-operation - and there is no risk of you breaching this order."

Pete arrived at the court, where more than 30 journalists and photographers awaited, wearing a black suit and his black fedora hat, smoking a cigarette.

Speaking in court, where he was representing himself, he said: "The people I’m closest to have had enough. They’ve said it’s drugs or them."

He also said: "A lot has changed in the past week."

The judge sympathised with him, saying: "It’s a hard road, isn’t it? It’s not easy.

"All we can do is provide the network. You have to do all the hard work."

Pete praised his doctor but admitted he hadn’t seen her recent review.

"I think you ought to," said the judge. "She refers to your journey out of addiction."

His next review in court is scheduled for October 17.

As he left, Pete posed and signed autographs for fans.

He was picked up in a black BMW. As he got into the car, he picked up a guitar and strummed a few notes to the press.

Pete court drug treatment review - April 18 2007
Pete Doherty will appear in court today after a judge previously said she was "optimistic" about his progress in beating his addiction to drugs.

The Babyshambles frontman attended a review of a drug treatment order before District Judge Jane McIvor at Thames Magistrates’ Court in east London in January.

The judge told the singer that she was even more optimistic than she had been at his previous review in October and, as a result, his case need not be reviewed as frequently.

"I would like to think it’s more optimistic than the last review in October," the district judge said previously.

She told Pete his doctor had referred to the "great effort" he was making to beat his addiction.

"But it’s a long process and there is another nine months to go," she said.

"This is more optimistic but we cannot take the pressure off. It takes day-to-day effort."

Defence counsel Bruce Clark agreed that the star’s progress was "encouraging".

"Most people would have failed by now," he told the judge.
