A key suspect wanted in connection with human trafficking and telecoms fraud cases - including that of Chinese actor Wang Xing - has been arrested and sent to China, Beijing's Ministry of Public Security said in a statement posted on its website on Sunday.

Police have detained a man suspected of involvement in the case of a Chinese actor who was duped into traveling to Thailand for a film job and then trafficked to Myanmar, China's Public Security Ministry said.

The ministry added that the suspect was surnamed Yan and returned to China on Saturday, but did not elaborate. Wang Xing, a 22-year-old Chinese actor, traveled to Thailand early this month after receiving an unsolicited offer to join a film that was shooting in Thailand.
