When students from Chelsea Heights Elementary School in Minnesota boarded a bus last month, a registered sex offender managed to get on undetected, too.
It started when the kindergarten students finished up a visit to the Walker Art Center in Minneapolis and got on the bus to return back to the school, according to WCCO.
The bus driver didn’t notice the man, 61-year-old Michael Charles Friedrichs, sitting in the back of the vehicle until they got all the way back onto school grounds.
The driver immediately contacted authorities, who arrested Friedrichs after discovering he was a registered sex offender.
According to Friedrichs’ record, his past crimes include exposing himself to children and engaging in sexual acts with two teenage boys.
Friedrichs said that he accidentally got on the wrong bus when leaving the Walker Art Center.
The St. Paul Public Schools district said it is now working to improve safety so that an incident like this doesn’t occur again.
Its statement said it has launched an investigation:
SPPS is conducting its own investigation to learn more about what happened and to strengthen our bus safety procedures. SPPS has also informed its school bus contractors about the incident to reinforce our required safety protocols.
Friedrichs was arrested on suspicion sex offender registration violation but was released from custody three days later because he wasn’t charged with a crime.
He was rearrested several days later for failing to disclose to authorities where he was living, which was in the terms of his predatory offender registration, Twin Cities Pioneer Press reported.
Friedrichs had a past history of masturbating in unoccupied buses.
