Brandon Hill, 18, of Byron Terrace, appeared at Dundee Sheriff Court on charges of indecency involving children.
Hill denies that between February 1 2016 and August 13 2017, at Byron Terrace, he caused a child over the age of 13 but under the age of 16 to look at an explicit sexual image of him he sent on social media.
He further denies, on the same date at the same place, causing the child to participate in sexual activity by requesting the child to send pictures with clothing removed to him on social media.
Hill also denies, on the same date and at the same address, threatening the child that unless he was sent further sexual images he would distribute the photograph over the internet and attempted to extort sexual images from the child. He will next appear on November 23.
