Police in the southern province of Binh Duong have arrested another man suspected of attacking a member of a volunteer anti-crime task force last month, the Tuoi Tre newspaper reported Thursday.
Pham Van Hoanh was the second person to be arrested for the assault on Nguyen Tang Tien, a member of An Binh Ward's Anti-crime Group in Di An Town on July 27.
Police had previously taken into custody Vu Duc Tuan, better known as Tuan the dog, and are now looking for Nguyen Van Nam, another suspect, the newspaper said.
Tuan told the police after Le Thi Lien, one of his gang members was caught stealing a motorbike on June 24 by Tien, he planned to take revenge on the latter along with Nam and Hoanh.
Tuan said while he gave them the scimitars, but did not directly join the assault. That day Nam rode Hoanh on a motorbike to Tien's bakery, where Hoanh slashed him repeatedly, Tuoi Tre quoted police as saying.
After the attack, they met Tuan to return the weapons to him, Tuan told police, adding that he'd then got rid of the weapons in Thu Duc District.
Tien, who also works as a xe om (motorbike taxi) driver, had told police that he was attacked by four masked men on two motorbikes.
The crime fighter was hospitalized with several serious injuries on his arms and legs. He received treatment under police protection and has since been released from the hospital.
The case has attracted a deal of media and public attention, raising concerns over rising crime and protecting people who act in public interest.
