A Toronto pediatrician is accused of possessing and accessing child sexual abuse and exploitation material after a Dropbox tip linked his account to suspected files. Toronto police began investigating Dr. Dilan Dissanayake, 45, on January 20, after a tip was forwarded through the U.S.-based National Center for Missing and Exploited Children. Police said the alert alleged a suspected CSAEM file was uploaded to Dissanayake’s personal Dropbox account on January 19 and logged in using an IP address geolocated to the Hospital for Sick Children. Court documents reviewed by CBC show that the detective described a five-minute video depicting a girl about 12 to 15 years old being sexually assaulted. The file name included the acronym “pthc,” police alleged. SickKids confirmed that Dissanayake, a staff rheumatologist, was placed on leave on January 28, the same day officers searched his office in the SickKids research centre. Investigators seized seven electronic devices from his home and two computers from his office during the January searches. A later warrant sought to seize a remaining work computer in late February, after police attested that seven more “thumbcache” images constituting CSAEM were found during an examination of a desktop computer seized from his office. The allegations have not been tested in court. Dissanayake and the College of Physicians and Surgeons of Ontario did not respond to CBC’s questions about whether he practiced medicine elsewhere after the investigation began. Dissanayake’s medical licence was not suspended until July, months after Toronto police started their probe. He has since been charged with possessing and accessing CSAEM. He remains charged as the investigation continues.
