Up to ten mobile phones and computer gadgets potentially linked to Rebekah Brooks have never been found by police, the hacking trial heard.

An iPhone, an iPad and "unknown device" listed on Brooks' home router were never recovered in searches on the former News International chief executive's office and addresses in London and Oxfordshire, Detective Constable Philip Stead told the court.

News International also provided details of three BlackBerry phones, an HTC phone, two Apple iPhones and an Apple iPad thought to be linked to Brooks.
