Appeal after Portadown stab murder
Politicians have called for an end to knife crime after a man was stabbed to death in Portadown.
Three men in their 20s have been arrested over the murder of the man, named locally as Mark Williamson.
The victim, thought to be 21, was attacked at around 4.20am in the Hartfield Avenue area of the Co Armagh town.
The men arrested in connection with the killing are aged 28, 26 and 24.
Alan Carson, DUP Mayor for the area, condemned the killing.
He said: "It has come as a shock to the local community and I would appeal for anyone with information to pass it to the police."
The murder came a day after police reported that three men were stabbed in a separate incident in Lurgan which left a 23-year-old man in a serious condition in hospital.
Sinn Fein's John O'Dowd said of the attacks: "It just shows the consequences of people using knives in this manner. The consequences are fatal and are devastating."
SDLP representative Dolores Kelly said: "This has proved to be an extremely violent weekend that has left one family in utter devastation and others in turmoil over loved ones," she said.
"Knife crime has become an increasing threat in our society and the carrying of knives can only lead one way. People need to recognise the consequences of their actions and the consequences of carrying knives."
