A man has been arrested in Ho Chi Minh City for allegedly supplying weapons to criminal gangs.

Police arrested Dao Trung Dung, 25, after monitoring his Facebook page for a month, one in which he advertised tasers, handcuffs, and pepper sprays.

Dung was caught Monday while delivering weapons to a customer.

He told the police he began getting supplies from a man in the north three months ago and the business has been profitable.

Most of his customers are criminal gangs, the police said.

Further investigations are going on.
