The 24-year-old was subjected to a two-hour ordeal by two men who approached him after he got out of a taxi in Glasgow at around 2.45am on Saturday.
They forced him to walk from Victoria Road in Govanhill to a cash machine in Albert Road, where he was made to withdraw a three-figure sum.
The men then forced their victim to walk towards an area of waste ground and later to his home, where they vandalised the property and stole his belongings.
Detectives want to speak to two people who they believe may have seen the robbery and abduction.
One was described as an Asian man in his late 50s who was wearing sandy coloured clothing and was walking up Albert Road.
The other was described only as a white man.
Detective Constable Natalie Carr, from Pollok CID, said: "This was a frightening ordeal for a young man and it's imperative we trace those responsible. I am appealing to the two men who were in the area at the time of the incident.
"I understand they may be frightened and may not wish to come forward and speak to police but I would appeal to them to please get in touch - a young man has been left extremely traumatised and frightened and it's imperative we get the people responsible for this incident."
The 24-year-old man was not injured during the ordeal.
The first suspect was described as Asian and in his mid-20s. He was wearing red jogging trousers and a white hooded track suit top - he kept his hood up throughout.
The second suspect is also described as Asian and in his late 20s. He was wearing dark coloured clothing and a black woolly beanie hat.
