Police have been combing a Dundee flat for evidence after a 32-year-old man was robbed there last night.
Video footage captured by the Tele shows officers leaving a block of flats, apparently with evidence from the brutal attack at 10.30pm yesterday.
The victim was robbed by three men who entered his home and threatened him before leaving with some items of personal property.
The incident happened in Balmoral Place, Douglas.
He was not injured, but was understandably shaken.
The people responsible are all described as being male, in their mid-30s, wearing dark hooded tops and spoke with Liverpool accents.
A comprehensive CCTV review of the area is being carried out.
Officers are also keen to trace a motorcyclist who was seen to drive along Balunie Avenue around the time of the incident, wearing dark clothing and a light-coloured, possibly white, helmet.
Anyone with any information that may be useful should contact Tayside Division on 101 quoting CR/12104/17 or speak to any police officer.
Alternatively information can be passed anonymously via the charity Crimestoppers on 0800 555 111.
