Pete Doherty is already on bail after being arrested last week

The Babyshambles frontman was arrested in east London after a newspaper published pictures allegedly showing him injecting drugs into a female fan.

He is already on police bail after being held on suspicion of possessing class A drugs last week.

Mr Doherty was arrested before he was due to play at an anti-racism concert in Trafalgar Square on Saturday.

A Scotland Yard spokeswoman said: "He was released on bail to return on a date in July pending further inquiries."
