Police investigating the murder of an Arbroath man are standing guard outside two properties in Kirriemuir.
The body of 27-year-old offshore worker Steven Donaldson was found at the RSPB Loch of Kinnordy nature reserve on the outskirts of Kirriemuir last Thursday.
Police said that Mr Donaldson had been the victim of a “brutal and sustained attack”.
A Police Scotland spokesman confirmed that officers were continuing to speak to a number of witnesses.
He added: “No arrests have been made at this time and inquiries are ongoing.”
But the Tele can reveal officers have been searching two homes in Kirriemuir and have been standing guard at the properties since the weekend.
A police spokesman confirmed that their presence at the two locations was “in connection with an ongoing investigation”.
Neighbours of one property confirmed that police had appeared over the weekend and taped off a large part of a yard and a house.
Roads into and around Kinnordy remained closed to the public.
Local residents said police had been at another property since Sunday.
One added: “There was a big van – that went away about 10am
“We saw men in white overalls – those white suits with hoods. They were out in the garden.”
Another resident said he had seen CID officers in the street on Sunday night.
He said: “They parked their car up here – it was CID and they were in plainclothes.”
Police have issued a fresh appeal for information in the wake of the fatal attack on Mr Donaldson, whose body was discovered at 5am on Thursday.
Senior investigating officer, Detective Superintendent James Smith of the Major Investigation Team, said: “Our thoughts and condolences remain with Steven’s family and friends during this time.
“I’d like to reassure the public that every effort is being made to trace whoever is responsible for his brutal murder.
“I’d like to thank the members of the public who have come forward so far.”
