A Schenectady man pleaded guilty on Thursday to child pornography charges.

Richard Nejame, 29, admitted that between October 2022 and May 1, 2023, he communicated with several girls over social media applications including Snapchat, while pretending to be a teenage boy.

Nejame encouraged the minor girls to take nude pictures and videos of themselves and send them to him, the U.S. Attorney’s Office said.

He also threatened to publish their pictures and videos on the internet if the girls did not comply with his demands, according to prosecutors.

Nejame faces up to 20 years in prison when sentenced on Aug. 14, and a possible lifetime of post-release supervision.
