A prolific paedophile in the UK has been sentenced to 32 years in prison.
Geophysicist Matthew Falder admitted to 137 offences, including blackmail, voyeurism and encouraging the rape of a child.
Posing as a female artist looking to do life drawings, 29-year-old Falder lured victims into sending him humiliating images, many of which ended up on the dark web.
He approached 300 people worldwide, some of them teens advertising for babysitting or dog walking jobs online.
Dr Matthew Falder hurt and humiliated more than 50 victims.
Falder also hid cameras in bathrooms to record women and girls naked. He even set up a camera in the home of his parents.
The judge branded Falder in sentencing him as an "internet highwayman,'' whose behaviour was "cunning, persistent, manipulative and cruel''.
He says the damage is ongoing for the victims, knowing the abuse caused by Falder still exists in other unknown persons' computers.
Falder had been working as a lecturer at the University of Birmingham when arrested by the NCA last year.
Adept at covering his tracks, he used 70 online identities ‑ careful not to leave tracks on the social media.
