We still need to speak to any witnesses who saw what happened who’ve not yet spoken to us, or anyone who may have video footage or photos of the incidents or the attacker.” A 23-year-old man died after being stabbed, and a man and a woman, aged 19 and 32, are in hospital in a critical condition after also being attacked. Five others were less seriously injured. — Agencies
