Troubled rocker Pete Doherty has been fined GBP100 ($200) for throwing rubbish from a car window in London. The Babyshambles singer was caught by police littering in London's Regents Park less than 24 hours after checking into rehab in North Yorkshire. Doherty - who has reportedly been dumped by supermodel Kate Moss - is believed to have sought treatment at the clinic under the order of a judge following a conviction for driving illegally while in the possession of Class A drugs last month (Jun07).
