A murder investigation has been launched after a second man died following a triple stabbing in Halifax.
West Yorkshire Police were called to Commercial Street at 3.48am on Sunday to reports that three men had been assaulted.
All of them were taken to hospital with stab wounds.
A 21-year-old man died in hospital a short time later, and police revealed on Monday that a 19-year-old also died late on Sunday evening.
A third man, aged 18, has received treatment for a non life-threatening injury.
Three men, two aged 18 and one aged 19, have been arrested and remain in police custody.
“This is an extremely serious incident which has resulted in the death of two young men and a further man injured,” said Detective Chief Inspector Matt Holdsworth.
Mr Holdsworth added: “We have specialist officers supporting both of their families and are determined to get answers for them and ensure that the person or people responsible are made to face justice for their actions.”
Police said a significant police presence was still in place at the scene on Monday morning.
They are appealing for anyone with phone video or dashcam footage to get in touch.
