Twenty-eight telecom fraud suspects were repatriated from Cambodia to southwest China's Chongqing Municipality Sunday morning, according to a source with the Chinese police.
The suspects are part of a group of 61 people caught in a China-Cambodia joint police operation earlier this month.
China's Ministry of Public Security, along with police from Chongqing Municipality and Shandong Province, began investigating the telecom fraud cases in early September.
The suspects allegedly made phone calls to people on the Chinese mainland cheating victims out of money by pretending to be law enforcement or with falsely promised high-return investments.
Bank cards, computers, and mobile phones involved in the cases were also seized.
In recent years, Chinese police have tracked down Chinese nationals hiding overseas who have participated in telecom fraud, mainly targeting victims on the mainland.
The police also had 74 suspects caught and repatriated from Cambodia in another operation early October.
