A registered sex offender in Yonkers has been sentenced to prison for sharing child pornography on social media.

Westchester County District Attorney Mimi Rocah says 41-year-old Demetrious Kotopoulos was already on probation for a prior sex offense conviction.

He will serve three to six years in state prison for uploading a file twice between March 2021 and April 2022 of a nude child engaged in sexual conduct to the social media platform Discord.

He also had a video of another child engaged in a sex act.

Kotopoulos didn’t disclose to the state that he created a new email address between March 2021 and April 2022 – a mandatory measure for sex offenders in New York. It was that new address where investigators found Kotopoulos’s Discord account.
