DES MOINES, IA (WFLA) – A scandalous blog featuring the backside of students at one Iowa high school is now under investigation by officials.

Officials at Saydel High School recently alerted a number of female students that photos of them were appearing on a Tumblr page.

The photos, taken without permission, were published on a page described as “creepshots by me from my school,” KCCI reported.

Donnie Dhabolt has three daughters at Saydel High. One of his daughters appeared on the blog.

“It makes me mad because my daughter feels unsafe in her own school,” said Dhabolt. “These are supposed to be places where we shouldn’t have problems with perverts.”

The Iowa station reported many of the photos, taken by another student, showed the backside of girls in yoga pants.

The school superintendent filed a complaint with Tumbler to have the page taken down. As of Wednesday morning, the page was no longer accessible.

One girl featured on the blog, who wished to remain anonymous, said she felt it was “degrading and embarrassing.”

Meanwhile, the sheriff’s office is investigating, but told KCCI no criminal charges have been filed as of yet because the students were all clothed in the photos.

School officials said they know who the student is behind the photo blog page but declined to say if he was being punished.WHAT OTHERS ARE CLICKING ON RIGHT NOW:
