Girl Throws Puppies in River in Video, 4chan Users on the Hunt

NEW YORK (CBS) A disturbing display of animal cruelty has surfaced online: a video apparently showing a young woman or girl throwing live puppies into a river.

In the 43-second clip, a girl with blonde hair, wearing a red-hooded sweater is seen grabbing six puppies from a white bucket and hurling them into a river.

At one point, someone can clearly be heard saying "whee!" while she hurls a black-and-white puppy into the water.

It is unclear if the video is legitimate or potentially a hoax.

The video was posted on YouTube, but has been taken down; it has since sparked an angry online crusade to identify the woman.

"Find this dumb little b***h and throw her into a river," one person wrote on the notorious Internet message board 4chan.

"Let's work together on exposing this sicko!" another comment read.

According to the Daily Telegraph, some comments claim the girl is from the Central Bosnian town of Bugojno, which has a population of 50,000.

4chan users are believed to have previously outed the British woman who was caught on tape apparently grabbing a cat by the scruff of its neck and dropping it in a garbage can before closing the lid and hurrying away down the street. Death threats against the alleged cat trasher were posted on 4chan and other online forums after the woman's name and address were apparently leaked online. She has since been given police protection.
