(CBS) – A Skokie podiatrist remained behind bars in Michigan Thursday for allegedly videotaping college wrestlers taking showers.

CBS 2’s Mike Puccinelli reports new information surfaced about similar allegations Ninos Jando faced in Illinois a few years ago.

Shackled and in his jail house blues, Jando went before a Muskegon County, Mich. Judge, accused of videotaping wrestlers at Muskegon Community College while they showered after practice.

Judge Maria Ladas Hoopes set Ninos Jando’s bond at $200,000. It stipulates the 34-year-old doctor not leave Michigan.

“I consider that to be a grave, grave concern for public safety,” Hoopes said.

Muskegon County prosecutors says Jando was caught after a wrestler spotted a light shining out of a toiletry bag that he had hung from a shower head. And prosecutors say their investigation is only beginning.

They say they have hours of videotape to go through and more than half a dozen cameras and recording devices and computers. They say it appears to have been going on for at least 10 years.

That’s because back in 2009, Jando was arrested in St. Charles after an off-duty cop noticed Jando acting suspiciously in the locker room of a club on Randall Road. Police recovered numerous videotapes at the time.

But Jando plea-bargained and ultimately pleaded guilty to disorderly conduct in Kane County Court.

Maat says police have already identified at least six victims on the tapes, and they expect they’ll find dozens more.

“These images could be worldwide and affect these innocent victims for the rest of their lives,” senior prosecutor Timothy Maat says.

If Jando is convicted, he faces up to five years in prison.
