Troubled rocker Pete Doherty was arrested Saturday as part of a police investigation into tabloid newspaper photos allegedly showing him injecting himself and a woman with drugs, police said.

Doherty, 27, was detained about 8 a.m. on suspicion of administering a noxious substance recklessly, a police official said, speaking on condition of anonymity because he was not authorized to identify the suspect.

Metropolitan Police said publicly only that the suspect was a 27-year-old man.

The Sun newspaper ran a photograph Friday that appeared to show Doherty holding a syringe to the arm of a woman lying on the floor. Another showed him with a needle to his arm.

The newspaper said the pictures were taken at Doherty's London home within the past five weeks.

Police said when the pictures appeared that officers from the Specialist Crime Directorate were investigating the newspaper's allegations.

Doherty's spokesman Tony Linkin could not be reached for comment.

Doherty has a well-documented history of drug use. He was most recently arrested for suspected drug possession on April 20, hours after a judge placed him on probation over separate drug charges.

Police found marijuana, heroin and crack cocaine in Doherty's car and clothing when he was arrested Dec. 18, one of a long line of run-ins with the law.

The former Libertines singer's drug problems gained international attention last year after a newspaper published pictures of then-girlfriend Kate Moss allegedly taking cocaine at a music studio where Doherty and his band, Babyshambles, were recording.
