The man who was murdered in Craigavon last night (Thursday, 16 January) was 25-year-old Nathan Gibson.
Nathan was found fatally wounded on the tow path near Lake Road and was pronounced dead at the scene.
Police are keen to trace his last known movements.
A 40-year-old man was arrested and he remains in police custody at this time.
Detective Chief Inspector John Caldwell said first and foremost his thoughts go out to the family of Nathan at this very sad time. He said police received a report late last night that Nathan had been attacked.
“I need to know the movements of Nathan last night between 5.30pm and 11.30pm. Did you see him? Was he in the company of anyone else? Did you see anything or anyone acting suspiciously in the area of the tow path from Legahory Court to the Lake Road area of Craigavon?” said Detective Chief Inspector Caldwell continued.
He said police are also investigating another incident at a house in the Legahory Court area of Craigavon.
“Whilst we cannot get into specific details of this incident we are also appealing to anyone who witnessed anyone acting in a suspicious manner in this area late last night to contact police.
“I would ask anyone who has information that could assist me with my enquiries to contact detectives from Serious Crime Branch at Lurgan PSNI Station on the non-emergency number 101, quoting reference 1741 16/01/20.
“Alternatively, information can also be provided to the independent charity Crimestoppers on 0800 555 111, which is 100% anonymous and gives people the power to speak up and stop crime,” he added.
