A Mahopac man faces federal charges for allegedly placing hidden cameras in a public bathroom to capture sexually explicit images of children.

Authorities say John Towers was arrested and charged Thursday with sexual exploitation of a minor and possession of child pornography.

The U.S. Attorney's Office says Towers used a bathroom in a privately-owned public park in Putnam County to place the hidden cameras between July 2018 and December 2019.

Authorities say they recovered a hard drive and found over 800 videos of girls using a bathroom.

Towers was arrested last month in Putnam County on separate charges.

He was on bail at the time of this most recent arrest.
