Officers were called shortly after 22:30 GMT on Oct. 31 to Park Road, where they said an unknown group had gained entry to the event¹.

Police said two boys remain in hospital with serious injuries, including one 17-year-old in a life-threatening condition, and that the other victims have been discharged¹.

A 17-year-old and a 16-year-old, both from Southampton, were arrested on suspicion of attempted murder and remain in custody, the BBC reported, matching Sky News' account of two arrests after five boys were stabbed^1,2.

Two witnesses told the BBC a fight started after a group came in over a garden fence, though they said the motive was unclear¹.

Police cordoned parts of Park Road and adjoining Valley Road¹.

Det Ch Insp Elizabeth Pirie said the arrests were a significant development but that police still wanted information from the community¹.

She asked anyone at the party who had not spoken to officers, and anyone with CCTV, phone, dash-cam or doorbell footage of Park Road and the surrounding area, to contact police¹.
