LONDON -- British police investigating computer hacking and privacy offences say they have arrested a journalist at his home.

Police say the 44-year-old man is suspected of perverting the course of justice. He is being questioned at a London police station Wednesday for alleged hacking related to the identification of an anonymous blogger in 2009.

The journalist is the 11th person to be arrested by detectives from Operation Tuleta, one of three parallel police investigations triggered by the phone-hacking scandal that has rocked Britain.

More than 40 people have been arrested in the probes of media wrongdoing and corruption. Criminal charges have been brought against suspects such as Rebekah Brooks, the former chief of News Corp.'s British operations.
