Massage Therapist Arrested for Sexual Assault on a Child -- Investigators believe there could be more victims
ACSO Investigators are asking for the public’s help in identifying additional victims of a licensed massage therapist who was arrested for sexual assault on a child. Christopher Ost, 39, is suspected of secretly videotaping clients – both adults and minors -- without their consent. Ost primarily provided massage services out of his home in Centennial, however, he also visited clients’ homes and provided massage services to special-needs children in the Denver metro area. He turned himself in to the Arapahoe County Detention Facility on December 7, 2025, and was charged with:
· Sexual Assault on a Child – 2 felony counts
· Invasion of Privacy for Sexual Gratification – 3 misdemeanor counts
He was held on a $75,000 bond but has since been released. His massage therapist license was suspended by the Colorado Department of Regulatory Agencies (DORA) on November 21, 2025, pending further investigation.
Investigators believe there may be additional victims. Anyone with information about Ost or who believes they may have been victimized is urged to contact the Arapahoe County Sheriff’s Office Tipline at 720-874-8477. Victims are also encouraged to file a complaint with DORA at: https://apps2.colorado.gov/dora/licensing/activities/complaint.aspx
This is an open and active case, and no further information will be released at this time. The filing of a criminal charge is merely a formal accusation. A defendant is presumed innocent unless proven guilty under Colorado law.
