A predator who groomed an under-age girl online and tried to murder her in the street has been jailed for 43 years. Ellis Dismore, 24, had sent threatening and disturbing voice messages to members of his victim's family before he repeatedly stabbed her, police said. The knife attack in broad daylight in Middlesbrough in June 2023 was captured on a passing motorist's dashcam, and the teenager was saved when members of the public stepped in to help. Dismore was found guilty of attempted murder and more than twenty other offences against young girls including stalking and making indecent photographs of a child. After he sent her relatives a series of chilling messages, the police were told about what was happening. A CPS spokesperson said: 'Ellis Dismore is a dangerous and violent sexual predator who manipulated his young victims into sexual activity through fear and intimidation. We sincerely hope that the part they have each played in jailing such a dangerous man will bring them some measure of comfort.'
