Police in the southern province of Binh Phuong on Tuesday said they are searching for six people who allegedly joined three others in robbing a man of more than VND3 billion (US$142,800) in July.
According to police, they have arrested three people, one of whom was 19-year-old Hoang Van Then, niece of the victim, Hoang Van Duong, 35.
Police said on July 18 at around 3 a.m., the gang broke into Duong's house in Loc Ninh District, tied his limbs and covered his mouth with sticking plaster.
They then took away a wooden chest filled with VND2.32 billion, 23.3 taels of gold, four silver bracelets and 10 silver coins.
After the thieves left, Duong untied himself and chased after them. However, he was attacked with tear gas and beaten, police said.
The arrested suspects told police the money was split between them.
The case is being investigated.
