[JURIST] Former Argentine police and army officer Ricardo Taddei, wanted by Argentina [JURIST news archive] for allegedly kidnapping and torturing 166 detainees during Argentina's 1976-1983 "dirty war" [GlobalSecurity.org backgrounder; JURIST news archive], was arrested in Spain Thursday. He is expected to appear before Spain's High Court, where he could be extradited to Argentina, though he could alternatively be charged in Spain as part of an investigation by Spanish Judge Baltasar Garzon into alleged crimes against humanity in Argentina and Chile. Last January, the Spanish High Court brought another former Argentinian military officer to trial [JURIST report] on genocide charges stemming from his involvement in the "dirty war." At least 9,000 Argentinians were tortured and "disappeared" by the Argentine military government in an attempt to silence leftist criticism of the military regime. Some human rights groups say the death toll was closer to 30,000. Reuters has more.
