A double murder investigation is underway in Surrey following the deaths of two men, both in their 20s, after a crash involving a black e-bike on Monday. One man died at the scene, while the other succumbed to injuries in the hospital. Four individuals have been arrested, including a 29-year-old man from Sunbury on suspicion of murder, a 24-year-old woman from North Yorkshire for assisting an offender, and two men, aged 24, from Walton-on-Thames and Feltham on suspicion of conspiracy to murder. Detectives are particularly interested in tracing the movements of a black e-bike and a black Ford Ranger in the area around the time of the incident. The investigation is in its early stages, and police have urged the public not to speculate or share distressing online content related to the victims. Authorities are seeking any witnesses or footage that could aid in understanding the incident.
