Li Furun was mauled by four dogs in a deserted factory while playing near his home in Handan, Hebei province, last Thursday, local police said this week.
The boy's body was found in the factory on Sunday about 1.5km away from his home, authorities said in a statement. The boy had been reported missing by his family three days earlier.
Police officers detained a person surnamed Fan, who owned all of the dogs. He is facing a potential charge of manslaughter, which could lead to a jail sentence of up to 7 years, according to Chinese law.
