Ohio police said Thursday that they are outraged over the treatment of a special needs student who had a bucket of feces and body fluids dumped on him in what he reportedly was told was part of the "Ice Bucket Challenge."

The Northeast Ohio Media Group reports that Bay Village police chief Mark Spaetzel says video of the incident is one of the most disturbing things he's seen in his career. He calls it "reprehensible."

Fox8.com in Cleveland reported this week that the autistic teen's mother discovered the video on his cellphone. She says her son was tricked into having feces, urine and spit dumped on him.

In the video, the boy with autism is seen standing in the driveway of a home off school grounds. He’s wearing only his underwear as a bucket of fluid is poured from the roof of the garage, Fox8.com reported.

"He was embarrassed because he did not know what the contents were until afterwards and then he didn't want anybody to know," the student's mother told the station. "They used his phone to tape it and they put it up on Instagram."

Spaetzel says police are investigating and will bring charges when they identify those responsible.

School officials say they will discipline any student involved.
