A DANGEROUS driver has been jailed after he mowed down a teenage student in a hit-and-run and left her to die alone in the middle of the road. Mohammed Youssaf has been sentenced to 30 months behind bars for ploughing in to 18-year-old Emma Guilbert as she walked through Fenham in November 2018. Newcastle Crown Court heard how the 33-year-old driver was believed to have been travelling at more than 40mph on the 30mph road when he struck the Newcastle University student at a pedestrian crossing on Wingrove Road. The impact of the collision was so great that Mrs Guilbert’s body came to rest more than 36 metres down the road.
