Former News of the World editor Rebekah Brooks was arrested Sunday in connection with British police investigations into phone hacking and police bribery.

Brooks' spokesman told CNN that she is being quizzed by police in London. She resigned Friday as the chief executive of Rupert Murdoch's News International. 

Her spokesman also told the site that Brooks was unaware she was about to be arrested and willingly showed up for an appointment with London police.

Police said Brooks is the eighth person arrested in connection with the phone-hacking probe and fourth arrested in the bribery investigation. Two people have been arrested on both accounts, meaning a total of 10 people have been arrested.

News International, which published News of the World along with several other papers, said they would "not tolerate wrongdoing" and would compensate those affected by their illegal phone hacking.

On Friday, Brooks said that as chief executive of the company, she felt "a deep sense of responsibility for the people we have hurt" and wanted to "reiterate how sorry I am for what we now know to have taken place."
