A video uploaded on social media on Saturday showed a Vietnamese man sitting with his hands tied behind his back in a trench in Nghia Tru Commune, Van Giang District, Hung Yen.
The 20-minute video captured a crowd of angered locals gathering nearby, hurling insults at the man, who was accused of being a dog thief, as he begged to be released, claiming he was innocent.
A body of a dead dog could also be seen in the trench, next to him.
Around 13 minutes into the footage, locals are seen pulling the victim out of the muddy water and dragging him into a nearby cage before locking the man inside next to the dog’s body.
The man displayed signs of mental instability during the event.
Initial police reports have identified the victim as a resident of Van Giang District, and local police said they were looking into the assault on Sunday.
Violence to the point of brutality against dog thieves are not uncommon in Vietnam, where an estimated five million dogs are slaughtered for food every year, many of which are stolen family pets and illegally-sourced dogs from neighboring countries, according to statistics by Asia Canine Protection Association.
