Two sickos grabbed a 12-year-old Russian schoolgirl off the street, dragged her around in a bag and raped her — filming the nine-hour ordeal to post online, according to published reports.

The girl was heading home from a music lesson about 5:30 p.m Tuesday in the Chkalovsky district of Russia’s fourth-largest city, Ekaterinburg, when the two approached, put a bag over her head and forced her into a car, Russian news website 66.RU reported.

They stuffed the girl into a large bag and carried her to an apartment, where they both raped her and filmed the attack, Metro UK reported. It wasn’t clear whether the attack was broadcast live.

The helpless victim was forced to hold a sign advertising a child abuse website, before her attackers thoroughly washed her in the bathroom, according to Metro. Then they shoved her back in the bag, drove her about 10 miles from where she was kidnapped and dumped her on the side of the road.

After three hours of struggling, she managed to free herself from the bag and flagged down police, according to the report.

She told police that one of her attackers was about 50 years old and wore “animal skin trousers,” the outlet reported.

Police spokesman Valery Gorelykh told Metro that about 200 police officers — and 50 detectives — were deployed for the investigation.

“We are using all our forces to uncover this horrendous crime,” he said.

Cops have urged drivers to hand over any dashcam footage that might show the suspects or their silver car. Forensic experts have collected biological material that may be able to help police identify the attackers’ DNA, the outlet reported.

One local mom told Metro she was feeling troubled after the appalling attack.

“There is fear and panic in this district,” she told Metro. “I am not allowing my 13-year-old daughter to walk to school and back alone.”
