Summary

Serial offender Ronaldo Otto, who goes by the name Samantha, has been jailed for five years after sexually assaulting a vulnerable autistic man. Otto, originally from the Philippines, was found guilty of sexually assaulting a 20-year-old autistic man on February 1, 2023, in a laneway in Dublin. The victim, who uses a disability card for the bus, was followed by Otto, who sat beside him and asked for his phone number. Otto then groped the victim and forced him down a laneway, where he performed oral sex on him. The victim reported the incident to his parents and attended the Sexual Assault Treatment Unit. CCTV footage and DNA evidence linked Otto to the crime. Otto had previously been given a suspended sentence for throwing boiling water on a man in 2019, but it was reactivated after he was convicted of another sexual assault in 2022. Judge Orla Crowe noted the victim was vulnerable due to his disability and described Otto's actions as predatory and intimidating.
