Police on Saturday rescued a 6-year-old Chinese boy who had been kidnapped two days earlier from a store near his home in Tokyo's Adachi Ward and held for a 15 million yen ransom, and arrested six people.

Police found the boy, He Risheng, at about 4 a.m. inside a condominium in Yokohama. They arrested one man and three women there on suspicion of kidnapping.

The four suspects are Wang Wengqin, 30, Zheng Zhen, 33, Yu Yunqin, 29, and Guo Yingyang, 26.
