Seven people have now been arrested after a man in his 20s was stabbed to death at a skate park, in an attack that also left a teenage boy fighting for his life.
Police confirmed this afternoon that seven people are now in custody, although no one has yet been charged in relation to the murder.
Four teenage boys aged 17, 16, 15 and 14 have been arrested on suspicion of murder, while two men aged 35 and 56 and a woman aged 33 have been arrested on suspicion of assisting an offender. All are from Northampton.
The arrests follow a fatal stabbing at Briar Hill Skate Park on Wednesday afternoon. Emergency services were called at 3:45pm after reports that two people had been knifed following an altercation at the park.
A man in his 20s was pronounced dead at the scene, while a teenage boy was rushed to hospital with life-threatening injuries. He remains in a critical condition.
The skate park has been sealed off with a police cordon, which remains in place as forensic and investigative work continues. Several nearby roads have been closed and members of the public have been urged to avoid the area.
