All three men were released from Bethnal Green police station pending analysis of the substances recovered, said a Scotland Yard spokeswoman, speaking on condition of anonymity in line with force policy. They must report back to police in December.

The troubled singer's battle with drug addiction has been lived in the public eye through countless media reports.

He has repeatedly sought treatment for his addiction and was expelled from band "The Libertines" in 2004, after band members issued an ultimatum for him to tackle his drug habit.

He was fined this month for assaulting a British Broadcasting Corp. reporter outside a London court.
