Publishing tycoon Rupert Murdoch is wanted for questioning by British police as part of an inquiry into alleged criminal activity at his newspapers.

The news comes after Murdoch's former News of the World editor Andy Coulson was found guilty on a charge of conspiracy to intercept communications at the Old Bailey in London on Tuesday (24Jun14).

Rebekah Brooks, the ex-News International chief executive and former editor of Murdoch's British newspapers The Sun and the News of the World, was cleared of all charges relating to the sensational phone-hacking trial.

According to reports, Murdoch was contacted by officers at Scotland Yard last year (13) but they agreed to his lawyer's request to wait until the trial was over to quiz the media mogul.

He is expected to be questioned "under caution" as part of their probe into alleged criminal activities at his British newspapers, and his son James, who was executive chairman of News International in the U.K., may also be interviewed.

In 2011, Murdoch and his son attended a British Parliament inquiry into the phone-hacking scandal, during which the tycoon was attacked by an interloper wielding a cream pie.

Stars including Hugh Grant, Jude Law, Sienna Miller and Steve Coogan were among the high-profile victims of the News of the World's hacking scandal. The publication was closed by Murdoch in 2011.

A jury is still deliberating further charges against Coulson, who denies allegations of conspiring to commit misconduct in a public office.
