Former News International chief executive Rebekah Brooks, who was arrested on Sunday over allegations of phone hacking and police corruption, has been released on bail, the Daily Mail reported.
Brooks, 43, spent some 12 hours in custody while being questioned.
She resigned on Friday in the wake of the growing scandal over phone hacking by journalists at the group’s newspapers.
Brooks, as well as News Corporation boss Rupert Murdoch and his son James, were summoned on Thursday to attend a parliamentary committee hearing on July 19 to give an account of the events surrounding News International.
The group has come under intense criticism by politicians in Britain after it emerged that some newspaper journalists employed by the group had written stories based on material hacked from phone messages, including those belonging to crime victims, celebrities and politicians.
The News of the World, the paper at the center of most of the allegations, closed a week ago after 168 years.
Brooks is a former editor of the paper, and another leading British tabloid, The Sun.
