Police at Cal Expo say 45-year-old Jeff William Jones of Sacramento targeted unsuspecting women with his hidden camera at this weekends’ County Fair.

"The camera was actually attached to his shoe and he was taking pictures of females private parts," says Robert Craft, Chief of the Cal Expo Police.

Police say Jeff Jones walked around the grounds placing his shoe with a microscopic camera underneath the dresses and skirts of women. They say the camera was attached to another recording device as he moved about the fair.

"He would put his foot near where the female was walking by," says Craft.

Then police say someone noticed what Jones was doing, called him on it, and the chase was on.

"Luckily our officers were close to the area and he pointed the gentleman out to us and we got in a foot pursuit because the suspect ran and we had to take him into custody forcibly," says Craft.

CBS 13 then learned what Mr. Jones does for a living. He's a counselor and trainer at the Sacramento Children's Home. He helps supervise kids who are survivors of severe abuse and neglect, and depend on intense counseling. Jamie Musuda who is a volunteer at the home is trouble by the arrest.

"You never want to hear about somebody doing that to anybody else," says Masuda.

Staff members at the children's home say Jones has a stellar reputation and a great example to the children and fellow employees.

"There's no reason to believe that any child was ever in danger around Mr. Jones. He's worked with groups of kids and staff and no known danger at all."
