Ann Arbor police arrested a man accused of sexually assaulting a child at Scarlett Middle School in Ann Arbor.
Jonathan James Green, 44, was taken into custody Sept. 11, two days after the crime allegedly occurred inside the building after hours.
Investigators said the school was open for a Parent Teacher Student Organization meeting.
It's a crime sending shock waves through a community known for its reputation for academic excellence.
"We all have to be vigilant and keep a watchful eye to protect our kids," Jason Engling, father of a seventh grader, said.
Engling said his wife was at the PTO meeting.
Green faces multiple felony charges including first degree criminal sexual conduct with a minor under 13.
A probable cause hearing is set for Sept. 19.
Engling said the the district is considering additional safety measures.
"That just tells me as a parent that I have to talk to him more about being aware of his surroundings," Engling said.
Action News' request for comment from the Ann Arbor School District was not immediately returned.
