The Scandal widens 10 arrests - London Chief Resigns

LONDON -- London's police chief has quit over his links to a former News of the World editor caught up in the phone hacking scandal.

Metropolitan Police commissioner Paul Stephenson denies any wrongdoing.

Stephenson has been criticized for hiring Neil Wallis, a former News of the World executive editor arrested last week in the scandal, as a part-time PR consultant for a year until September 2010.

He said he did not make the decision to hire Wallis, and had no knowledge of Wallis's links to phone hacking.
