Five teenagers were stabbed at a Halloween party in Chandler's Ford, Hampshire, on Saturday night, police said. Officers responded to Park Road, near Eastleigh, shortly after 22:30 GMT. The injured teens included three boys aged 16 and two aged 17, all taken to hospital with serious injuries. Hampshire Police said an unknown group gained entry to the party before the stabbings occurred. An eyewitness told the BBC that ambulances and an air ambulance attended the scene. Another witness reported seeing someone running from the house, shouting that he had been stabbed and was being chased by two people. Police maintained a cordon on Sunday as the investigation continued and appealed for witnesses and information. Eastleigh MP Liz Jarvis told the BBC the community was in shock and urged people to avoid sharing information online and allow police to work. Two local churches opened their doors to offer support to residents.
