British Rocker Pete Doherty Released on Bail

British rocker Pete Doherty was released on bail Sunday by police investigating tabloid newspaper photos that showed him injecting himself and a woman with drugs, a police official said.

The Babyshambles singer was detained Saturday morning on suspicion of recklessly administering a noxious substance, the official said, speaking on condition of anonymity because he was not authorized to identify the suspect.

Doherty, 27, is to return for questioning in July, the official said.

The Sun newspaper published a photo 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 pictures were taken at the singer's London home in the past five weeks, the paper said.

Doherty was previously arrested April 20 for suspected drug possession, hours after a judge placed him on probation on 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.

Last year, a newspaper published pictures of model Kate Moss, his girlfriend at the time, apparently using cocaine at a music studio where Doherty and his band were recording.
