SHIJIAZHUANG, Jan. 20 -- A court in north China on Monday sentenced a man to life imprisonment for adding poison to frozen dumplings that left four Chinese and nine Japanese citizens ill.

Lyu Yueting was found guilty of adding dangerous substances to food, which resulted in one person being seriously ill and 12 others with minor illnesses, as well as significant losses of property, from December 2007 to January 2008, the Shijiazhuang Municipal People's Procuratorate told Xinhua.

It is not clear if Lyu plans to appeal.
