Police are appealing for help as they try to piece together the final movements of a Polish man found dead in an Aberdeen flat.
Wieslaw Koziolek was found dead on Monday afternoon, and officers quickly announced they were treating the incident as suspicious.
Detectives have now revealed the 49-year-old was seen on Victoria Road, close to its junction with Grampian Road, at about 9.55am on the day he died.
It is believed he spent some time in the city centre beforehand, and then returned to Torry on foot.
Detective Chief Inspector Iain Smith, who is leading the inquiry, said: “We know that Mr Koziolek was in Aberdeen city centre at about 9.15am where he remained for a short time before returning to Torry where he was last seen at 9.55am.
“His last movements could be key to our inquiries and we would appeal for anyone who may have seen him in either the city centre or on his return to Torry, to get in touch with us as soon as they can.”
Police and paramedics were called to a flat in Balnagask Avenue at about 2.10pm on Monday, but Mr Koziolek was already dead.
It is understood Mr Koziolek, who was living in a temporary accommodation for the homeless, suffered stab wounds.
A huge investigation was launched after the discovery, with police sealing off parts of the block of flats as search officers and a forensic team hunted for clues.
DCI Smith added that officers from the major investigation team were being supported by local policing teams as the inquiry continues, and that officers were carrying out additional patrols in the Torry area to reassure the public.
He also made a plea to any members of the Polish community who may have information to contact the police.
Anyone with any information can contact the police on 101 or Crimestoppers on 0800 555 111.
