Following a High Court hearing in May 2011, Sienna Miller was awarded £100,000 in damages from News of the World after the newspaper admitted hacking into her phone. Later, as a core participant, she gave evidence to the Leveson Inquiry in November 2011, including the following:
I would often find myself almost daily, I was 21, at midnight running down a dark street on my own with 10 big men chasing me. The fact that they had cameras in their hands meant that was legal. But if you take away the cameras, what have you got? You've got a pack of men chasing a woman, and obviously that's a very intimidating situation to be in.
