Drug gang leader launched fatal attacks

In 2011, two Chinese cargo ships refused to pay protection money to a drug-trafficking gang on the Mekong River.

Naw Kham, the leader of the gang, swore to take revenge.

On Oct 5, the Hua Ping and Yu Xing 8, which had refused to pay for protection, were attacked and 13 Chinese fishermen aboard were murdered. Their bodies were found floating on the river, with the eyes and mouths covered with black tape and the hands bound.
