A Peruvian man was sentenced Tuesday to life in prison for sexually assaulting and killing a 7-year-old girl in the city of Hiroshima last November in a case that led to a clampdown on immigration rules.

The crime by Jose Manuel Torres Yagi, 34, was "vicious and coldblooded" and he had intended to molest and kill Airi Kinoshita, presiding Judge Hiromichi Iwakura of the Hiroshima District Court said, rejecting the defense argument that he bore no intent.

Prosecutors had demanded he be put to death.
