A dispute over an 11 billion VND debt with gang leader Hanh "Su" led Vu Quang Chien to open fire at a beer quan in Hanoi, injuring one person and resulting in a 12-year prison sentence.
A friend borrowed money from crime boss Hanh "Su" and fled, leaving Vu Quang Chien responsible for repayment. This led to a conflict, escalating into a shooting outside a beer establishment.
