An American mother who hired a therapist to help treat her autistic son was confused as to why the sessions weren’t resulting in any improvement.

Suspicious, she decided to leave a hidden camera in the room where the ‘therapy sessions’ took place and was shocked to see the way in which the ‘therapist’, Stephen Jacobs, abused her son.

Instead of treating him, Jacobs can be seen elbowing 3-year-old Caden, hitting him with pillows and even head-butting him.

WISN NEWS 2 reports that Jacobs is now facing felony charges of abusing a child during a therapy session.
