BHP Billiton faces an investigation into its possible role in the forced eviction of the population of a Colombian town that was then bulldozed to make way for a coalmine. The investigation [is] by the Organisation for Economic Co-operation & Development... But BHP yesterday said the forced eviction of the Tabaco township predated its involvement in the current Cerrejon mine, and it rejected claims that Cerrejon was now trying to strangle other townships... The other equal partners in Cerrejon are...Xstrata and...Anglo-American... BHP's head of community relations, Ian Wood, acknowledged there were "legacy issues" over Tabaco, but said BHP and its partners were already working with former residents to address concerns.
