Basque news channel Euskal Irrati Telebista has reported that a small explosive device was detonated at the Spanish-owned BH factory in the Basque city of Vitoria-Gasteiz. The Interior Department of the Basque government attributes the attack to the Basque seperatist group ETA. BH is the bike sponsor of the Liberty Seguros team. Team leader Roberto Heras won this year's Tour of Spain but since then one of his urine samples has tested non-negative for EPO.
