Pete Doherty failed to appear at a London court Wednesday for a review of his progress in drug rehabilitation.
Doherty’s representatives told Thames Magistrates’ Court that he had been unable to return from Paris, where his group, Babyshambles, had played a concert Tuesday night.
The case was adjourned until May 12.
Doherty, 27, was sentenced in February to 12 months of community service and ordered to submit to regular drug tests after pleading guilty to drug offenses.
He faces an April 20 appearance in the same court on separate drug charges. Doherty pleaded guilty last month to seven charges of possessing drugs including heroin, crack cocaine and marijuana.
His drug problems gained international attention after a newspaper published photos of then-girlfriend Kate Moss allegedly using cocaine at a music studio where Doherty and Babyshambles were recording.
