Five people were injured in what Hampshire Police called a serious assault overnight on Halloween in Chandler's Ford, near Eastleigh in southern England, with officers still at a cordon on Park Road on Sunday¹.

Sky News reported that five teenage boys — three 16-year-olds and two 17-year-olds — were taken to hospital with serious injuries after being stabbed at a party, and that police were called just after 10:30 p.m. Saturday².

The BBC did not independently confirm a stabbing in its police account¹. An eyewitness told the BBC that ambulances and an air ambulance attended and that teenagers at a party in the area were heard saying they had been stabbed¹.

Sky News said officers established that an unknown group had gained entry to the party². Hampshire's Eastleigh team said the incident would be concerning for residents and that it was investigating the circumstances¹.

Senior investigating officer DCI Elizabeth Pirie, quoted by Sky News, asked people who were at the party, or who had relevant footage, to contact police². "We particularly want to hear from anyone who can provide information to support our investigation," she said².

Pirie also asked for CCTV, mobile phone, dashcam or doorbell video covering Park Road and nearby streets². Police remained at the scene on Sunday as inquiries continued^1,2.

No arrests, suspect descriptions or updates on the condition of those injured were given in the two reports^1,2.
