A 21-year-old man has been jailed after sending an obscene video to a teacher and then blackmailing her into sharing it with students, leading to the victim losing his job and attempting to take his own life.Muawiya Amin, from Allanton, Derbyshire, posed as a woman on Instagram and had a conversation with the teacher which turned sexual. During the exchange, the victim sent a video of himself performing a sexual act at his workplace.Prosecutors told Derby Crown Court that Amin later demanded £1,000 to stop the footage being shared. The teacher paid £400 via PayPal in an effort to stop the video being released and contacted police the same day, The Sun reports.Despite receiving payment, Amin continued to distribute the footage to the teacher’s students. The victim, who remained anonymous throughout his life, was dismissed from his job and later attempted suicide.Sentencing Amin to 15 months in prison, Judge Shaun Smith Casey described his actions as “depraved behaviour”.“He went through all the concerns about his privacy, reputation and personal safety,” the judge said. “Even when the money was paid you still sent it.”He said the consequences for the victim were serious.The judge said, “His work was done, but the worst part was that on the night it was published, he tried to take his own life.” “You knew what you were doing and you achieved it.”In a statement read out in court, the victim described the emotional impact of the incident, saying he suffered extreme distress and felt his life had been destroyed.Amin admitted to blackmailing. His defense said that he had acted under pressure and was trying to get along with people he considered his friends.“He fully accepts that his actions were wrong and he is responsible,” his lawyer told the court. He said that he has the support of his family and is working in the family business.The court heard the victim survived after someone contacted him on the night he attempted to take his own life.This case highlights the serious consequences of online exploitation and blackmail, especially when victims are targeted through social media platforms.
