Beijing, June 1 (IANS) As many as 31 infants were rescued after police busted a child trafficking ring in China's Yunnan province, the government said Friday.

According to railway ministry's public security bureau, the gang abducted babies in Yunnan and sold them in Hebei and Shandong provinces, Xinhua reported.

The railway police have arrested 76 people so far by travelling to seven cities of the three provinces since November 2011 to bust the ring.

The gang would purchase an infant for 8,000 to 10,000 yuan (about $1,200 to $1,600) in Yunnan and sell it in Hebei and Shandong for 20,000 to 50,000 yuan, according to the bureau.

The ring involves members who abduct, purchase, transport and sell the infants to adoptees, said Wang Ansi, an official.
