A suspected leader of a Mexican drug cartel was arrested at Amsterdam Airport Schiphol at the request of the United States, according to dpa. Jose Rodrigo Arechiga Gamboa, 33, was taken into custody Monday after he disembarked from a plane from Mexico City, said the US Attorney's Office in San Diego, which is seeking his extradition. Arechiga Gamboa, who was travelling under a false name, is accused of being a top enforcer for the Sinaloa Cartel, headquartered in the western Mexican state of Sinaloa. He was charged last month in the United States with conspiracy to distribute drugs and conspiracy to import them, according to an indictment unsealed Friday. Dutch border police had said they had taken an internationally sought Mexican suspect into custody at the beginning of this week. The Dutch Justice Ministry is studying the extradition request, the Dutch ANP news agency reported. Arechiga Gamboa allegedly is one of two leaders of a Sinaloa Cartel hit squad, earning him the nickname "Chino Antrax" after the usually lethal disease anthrax, Mexican media reports said. The squad has been blamed for numerous killings.
