(Beaverton, OR) -- A former Nike employee is accused of recording dozens of victims in secret bathroom videos. The Washington County Sheriff's Office says 27-year-old Khoi Troung of Portland used his cell phone to record at least 50 men in restrooms. Troung worked in the Nike Air Manufacturing Innovation building and the incidents happened between 2017 and 2018. Nike terminated Truong in 2018, but no one reported his conduct to law enforcement. Detectives learned about what happened during an unrelated investigation.
