Durham Regional Police have arrested an Oshawa man on serious charges after a disturbing incident involving a woman who was living in his home as a child-care provider. The case has raised concerns about the safety of informal caregiving arrangements and prompted investigators to seek potential additional victims.
Derek Bellamy, 38, of Oshawa, was arrested on Wednesday and faces charges of sexual assault and child exploitation. According to Durham Regional Police, the investigation began after a woman who had traveled to Canada in December 2025 sought medical attention following a troubling incident at the family's home.
The woman had connected with a couple through a Facebook group and came to Canada to work as an au pair — a live-in caregiver who provides child care in exchange for room and board. She moved into the family's Oshawa home and began helping care for their children under this informal arrangement.
Police allege that on December 12, 2025, Bellamy gave the woman ice cream. Shortly after consuming it, she began feeling incoherent before losing consciousness. When she regained awareness, she had no memory of what had transpired during the rest of that night.
Recognizing something was seriously wrong, the woman sought medical attention. Tests later confirmed that a noxious substance was present in her system, according to investigators. Durham Police have confirmed that the sexual assault charge relates directly to this woman.
In early 2026, investigators executed a search warrant at the family's Oshawa residence. During the search, police seized electronic devices and what they describe as the same drug allegedly used in the December incident. The investigation took a more troubling turn when evidence found on those devices not only supported the sexual assault investigation but also revealed child sexual abuse and exploitation material.
Bellamy was held for a bail hearing following his arrest. Police have released his photo as part of their ongoing investigation, expressing concern that there may be additional victims who have not yet come forward.
The case highlights the vulnerabilities that can exist in informal caregiving arrangements, particularly for individuals who may be new to Canada and unfamiliar with local support systems. Au pair arrangements, while common, often operate outside formal employment structures, which can leave caregivers in precarious situations.
Anyone with information about this investigation or potential additional victims is encouraged to contact Durham Regional Police. The allegations against Bellamy have not been proven in court.
