Police in London are searching for a Nigerian man, Temitope Segun, after he escapes from custodial transport. Reports say the incident occurs in the Plumstead area of southeast London, where Segun escaped from a prison van while in police custody. Following the escape, UK police launch a manhunt to locate him. The available accounts describe Segun as a 25-year-old prisoner and indicate that officers are working to track his whereabouts. Both sources frame the incident as an ongoing search, with authorities treating it as an active escape from custody rather than a resolved case. The reports do not provide details on the circumstances that enabled the escape, his charges, or his current status at the time of publication. No information is included in the excerpts about injuries, potential victims, or specific law-enforcement actions beyond the manhunt.
