Police in Ho Chi Minh City on Wednesday arrested five suspects who allegedly sold spyware to customers to secretly monitor other people’s phones.
Four of the suspects are members in the same family, including Le Kim Dinh, 33, and his wife Nguyen Thi Hue, 29. The other is their employee Nguyen Van Nguyen, 25.
Police caught the group red-handed while they were installing spyware for some customers on Wednesday morning.
According to police, the ring helped thousands of customers track and tap smartphones.
Most of the customers paid VND1.5 million (US$66) per month to keep tabs on their spouses and business rivals.
The ring advertised their illegal service on several websites, prompting the police to launch an investigation.
Police said the ring had bought the spyware from overseas.
In late October, Ho Chi Minh City police also busted another illegal company, seizing three men who allegedly supplied services for tracking, tapping and secretly filming others.
