A former private investigator has been arrested as part of a national inquiry into allegations of computer hacking and other breaches of privacy.

The 58-year-old who is now retired, was arrested by police officers at his home in Reading, Berkshire, early this morning on suspicion of trying to illegally access information.

He is the 21st person to be arrested as part of Operation Tuleta, the Scotland Yard investigation that is being run alongside inquiries into alleged phone hacking and corrupt payments to public officials.

The inquiry became caught up in a row between MPs and investigators over whether to publish a list of clients of rogue private investigators.

Earlier this month, Scotland Yard removed nine names from the list, including five linked to Operation Tuleta, because they are subject to live investigations.
