Police are investigating multiple hit-and-run incidents involving serious injuries to pedestrians and cyclists across the UK. In Bradford, a 17-year-old male remains in critical condition after being struck by a speeding vehicle that fled the scene, prompting West Yorkshire Police to issue an appeal for witnesses and dashcam footage. Meanwhile, in Oxford, a woman in her 60s was hit by a black pickup truck while riding her bicycle, with authorities searching for the driver who left without stopping. Additionally, in Wallingford, a cyclist in his 70s was also critically injured after being struck by a white, long-wheelbase van that did not remain at the scene; police are appealing for information about this incident as well. All three cases highlight growing concerns over road safety and the implications of hit-and-run accidents. Authorities urge anyone with relevant information to come forward to assist in their investigations.
