Chinese police escorted a leader of a criminal group involved in human trafficking and forced prostitution back to China from the Philippines on Thursday night, according to a statement issued on Friday by the Ministry of Public Security.

Wang Wanning, 43, was suspected of crimes related to human trafficking and forced prostitution in Chongqing Municipality from 1994 to 2009.

She fled to the Philippines after police began an investigation in 2009.

One of her victims was a woman who was put under house arrest for 6 years. Another woman suffered a mental breakdown and many others were beaten for trying to escape Wang's gang.

Wang's gang raked in over 100 million yuan (15.2 million U.S. dollars) over the course of several years, due to their involvement in prostitution and other illegal endeavors.

The ministry worked with Chongqing police to dispatch seven policemen to the Philippines on March 23, resulting in Wang's Wednesday capture. Wang was escorted home on Thursday.
