THREE teenagers have been locked up for a "terrifying" knifepoint robbery in Keighley. Byron Bell, 18, of Wrose Road, Bradford, Mohammed Fellows, 19, of Granville Road, Bradford, and Liam Karolyi, 18, of Morrison Avenue in Rotherham were charged by police after targeting a vulnerable adult. The incident happened on April 11 this year when the suspects entered a flat on Aireville Road in Keighley. They pinned their 57-year-old male victim down onto his bed and held a knife to his throat, whilst the others stole the TV from his room. The victim suffered a cut to his neck, which required surgery, as a result of the incident.
