Sneaky Hat, a Facebook craze that originated in Queensland, Australia, encouraging teenagers to post pictures of themselves nude on the Internet, is being investigated by the police.

It's a Facebook page dedicated for teenagers to take pictures of themselves wearing nothing but hats over their private parts. Cyber safety experts have stated that the Queensland teenagers behind it and contributors to the Web site could face child pornography charges.

The original page was started by 15-year-old students from Dalby, Queensland, for fun but it rapidly attracted about 100 photos of their friends in the Sneaky Hat pose with more than 10,000 followers.

As of now, the original page has been locked and shut down. However, many recreations have been spawned and a blogspot site was also created with all the uploaded pictures.

Check out the video given below, which is a compilation of some of the photos.
