MEXICO CITY-Mexican authorities have arrested five people over the deadly kidnapping of a group of Americans, after the suspects were left in the street with their hands tied by alleged cartel members, officials said Saturday. The four US citizens, two of whom died, were snatched at gunpoint after crossing the border into crime-plagued Tamaulipas state on Friday in a minivan, apparently so that one could have cosmetic surgery. Tamaulipas prosecutor Irving Barrios said that a warrant had been executed for five people for the crimes of kidnapping and homicide. They are the same five men who were found Thursday with their hands bound on a street in the city of Matamoros, apparently dumped by fellow members of the Gulf Cartel, a source in the prosecutor’s office told.
