Police have named the man whose body was found in a local house last night.
He has now been named as John Donnachy and the death is now being treated as suspicious.
Detective Chief Inspector Andrew Patrick from Police Scotland’s Major Investigation Team said: “Following the discovery of a man’s body within a property in Hazel Court in Alyth, I can now confirm that we are treating his death as suspicious and have launched a major investigation to determine the full circumstances.
“I can also confirm that the man who has sadly died is John Donachy, who was local to the area.
“John would have been known to members of the local community and I am appealing for anyone who saw John anytime on Friday or Saturday to contact us as soon as possible with information about where they saw him and any other details they may have.
“John would have been wearing a dark coloured jacket, dark trousers and green wellies.
“If anyone recalls seeing John in and around Alyth I would ask them to get in touch. Having the knowledge of where he was and approximate timings could be very useful to our investigation.
“Incidents like this are extremely rare in Perth and Kinross and I would like to stress that this has been an isolated and contained incident.”
Locals reported a big police presence, with at least six cops on patrol and forensics operating from a large police patrol vehicle combing the area.
The area is taped off and forensic officers in white suits and masks combing the ground.
DC Patrick added: “There has been a police presence in the area of Hazel Court since last night and this will continue for the time being. I would like to again, thank the local community for their patience and understanding whilst we carry out our investigation.”
Hazel Court is a street of terraced houses off Airlie Street not far from the town centre.
It remains sealed off this afternoon as cops probe the area of a pend linking Hazel Court to a car park.
Neighbours said they had been awoken during the night by the police activity.
David Chalmers, 83, has lived on nearby Isla Street since 1972, when the scheme was built.
He told the Tele: “The last time there were this many police around here was for a murder 30 years ago.
“There’s been a dozen police on duty all the time. The big command unit van has been sitting there since before midnight.
“At one time I counted eight policemen outside in yellow jackets.
“We hardly ever see a policeman up here so to see this big police presence is unusual.
“There doesn’t seem to be much crime in this area. The biggest problem we have is drugs but you get that everywhere.”
Perth and Kinross Inspector Robert Prudom added: “Officers from the community policing team will be carrying out high visibility patrols in the area to provide reassurance and be available to help and speak to any resident.
“If you believe you can assist with this enquiry then please call Police Scotland on 101 quoting reference 4045 of 3 March, speak to any officer or make an anonymous report to Crimestoppers on 0800 555 111.”
