Because of his doping offense all the medals of 2002/ 03 were withdrawn subsequently.
In October 2003, Chambers tested positive for the steroid tetrahydrogestrinone. After a hearing on 22 February 2004, the British Athletics Federation detained him for two years. The IAAF also nullified his every mileages between 1 January 2002 and 1 August 2003 including the leveling of the Europa cup record of Linford Christie on 14 September 2002. Chambers' coach Remi Korchemny was at the Bay Area Laboratory Co - Operative ( BALCO ) involved; against this company ran in the United States because of a criminal investigation into illegal trafficking of doping substances.
