Police in the central province of Binh Dinh on Sunday found the body of an eight-year-old boy who was allegedly killed by a 22-year-old student.
According to police, initial information shows that Dang Van Cuu, student of Quy Nhon University, kidnapped Nguyen Viet Dung from school on November 11. He then took Dung to a beach in Quy Nhon Town, where he strangled the child with a shirt before hitting him to death on his head with a rock.
Police said after the murder, Cuong bought a mobile phone SIM card and sent text message threats to Dung's father, Nguyen Viet Cuong.
Cuu, who is now in custody, said he wanted revenge for scoldings he received when he worked part-time for Cuong.
The case is now under investigation.
