A Vietnamese factory worker was killed after falling into a giant industrial shredder, with a horrific video showing the moment he was sucked into the machine.

Ro Mah J, 34, was standing inside a large container feeding material into the machine just after 6 a.m. Thursday when his tool suddenly got stuck, local outlet Dan Tri reported.

He frantically tried to yank his tool out of the shredder before being dragged into the machine at the Chanh Tay Gia Lai Joint Stock Company plant, disappearing out of shot.

Seconds later, a spurt of water shot out of the container.

Ro was pronounced dead at the scene and a police investigation into the accident is underway.
