Rebekah Brooks was sensationally arrested Sunday in London. She's the 10th person arrested in the exploding phone hacking scandal that is threatening to take down Rupert Murdoch's worldwide media empire.

Brooks, who was editor of News of the World at the time a reporter hacked into the phone messages of a murdered teenage girl and went on to become one of Murdoch's top corporate officers, went to a London police station today for a pre-arranged interview. She was unexpectedly arrested on the spot.

Brooks had been expected to testify before Parliament Tuesday along with Rupert Murdoch and his son James.

The scandal has already moved onto U.S. soil. As RadarOnline.com previously reported, Les Hinton, the CEO of the Murdoch-owned Dow Jones -- publisher of The Wall Street Journal -- has resigned.

And Hollywood is on board as well. Actor Jude Law has sued Murdoch's Sun newspaper, alleging it hacked into his phone in 2005 while he was in New York.

Rupert Murdoch says he's sorry. The embattled media mogul published a full page apology in his UK newspapers, The Sun and The Times of London on Saturday.

"We are sorry for the serious wrongdoings that occurred," the letter said.  "We regret not acting faster to sort things out."

The phone hacking scandal that has turned Murdoch's media empire on its head, and resulted in the closing of his News of the World newspaper, on Friday continued to snowball with two of his top lieutenants resigning.

Les Hinton, CEO of Dow Jones -- publisher of The Wall Street Journal -- ended his 52-year career with Murdoch. And Rebekah Brooks, CEO of Murdoch's News International, also handed in her termination papers.

Murdoch is scheduled to appear before the British Parliament on Tuesday, but there is no indication his published mea culpa is going to be nearly enough to placate the outraged public.
