A school custodian in Westborough was arrested on Thursday for possession of child pornography following an investigation by the Massachusetts State Police Cyber Crime Unit.
The investigation began back in August, when the Massachusetts State Police Cyber Crime Unit received a tip from the National Center for Missing and Exploited Children regarding suspicious activity related to child pornography on a personal cloud storage account.
Troopers traced the activity to an IP address associated with a residence in Westborough, where the suspect, 25-year-old Luis Guncay-Barros, was identified.
Under federal law, electronic service providers are required to report such activities to the National Center for Missing and Exploited Children, which led to the involvement of the Massachusetts State Police.
Troopers secured a warrant for the suspect's cloud storage and discovered child pornography matching the initial tip from NCMEC.
Further investigation revealed that Guncay-Barros had accepted a job at a technical high school, raising concerns due to his access to children.
Then, on October 9, law enforcement, including the United States Secret Service and Westborough Police Department, executed a search warrant at the suspect's residence, establishing probable cause for his arrest.
State and local police have notified the school community where Guncay-Barros worked as a custodian.
Assabet Valley Regional School District Superintendent Ernest Houle issued the following statement:
Guncay-Barros was transported to the Millbury Barracks and arraigned in Westborough District Court.
