A man in Vietnam's Dong Nai Province has allegedly confessed to accidentally killing the mother of a high school student with an explosive package he built for a romantic rival.
Police say Nguyen Thanh Thanh, 21, studied bomb-making online and planting an explosive package in the Doan Ket High School teachers tenement in Tan Phu district.
His expected target, Hoang, was a male teacher who had begun dating Thanh’s ex-girlfriend.
Pham Thi Lan, one of Hoang's neighbors and colleagues, had the misfortune to spot the package early Thursday morning.
Believing the package to be a gift for her daughter-in-law (a teacher at the school) Lan opened and detonated the device.
Police say the explosion killed her, instantly.
The incident occurred on Teacher’s day (November 20) a national holiday during which students present their teachers with flowers or gifts to express their gratitude.
Thanh was arrested in Ho Chi Minh City, where police say he'd planned to hide out.
