A man has been stabbed to death after being asked for help when fighting broke out at a neighbour’s house party.
The 50-year-old was attacked by a group of about five men and women as he approached the house in Brooklyn Road, Cleckheaton, shortly after midnight.
He suffered stab wounds to his back and died later at Dewsbury hospital.
Det Ch Insp Simon Bottomley, of West Yorkshire Police, said: “This was a vicious attack which resulted in a man losing his life.”
Police said the victim would be formally identified after a post-mortem examination which was due to take place later.
Det Ch Insp Bottomley said: “At this stage of the investigation we believe that, following some disorder at a house party, the victim had been on his way to help.
“As a result, he was set upon by what we believe to be a group of five men and women and subsequently received stab wounds to his back.
“There were a lot of people in the street at the time of this attack and I urge them or anyone else who can assist us with this inquiry to contact police.”
