A Sycamore man was arrested Sunday after police investigated alleged sex offenses against a child.

Mark Baumann, 44, faces three counts of predatory criminal sexual assault of a child, three counts of aggravated criminal sexual abuse and possession of firearm ammunition without FOID card. Baumann’s bond has been set at $3 million.

A Sycamore school resource officer was notified of an alleged sexual assault that occurred between July 2011 and September 2012, according to a Sycamore Police Department news release. Baumann was arrested shortly after a victim-sensitive interview was conducted at the Children’s Advocacy Center, according to Sycamore police.

“The case is a perfect example of how important it is to have a school resource officer available to the children of our community,” said Sgt. Rod Swartzendruber, according to Sycamore police.
