Vulnerable people have been warned to be on their guard against bogus callers after a spate of incidents.
Police said the conman targeted several elderly people after tricking his way into properties on the south side of the city. Since January 22, detectives have received calls from elderly residents in the Mosspark and Craigton areas.
But Detective Constable Kenneth Johnston believes there may be more victims.
He said: "It is despicable this man is targeting elderly and vulnerable members of the community."
All incidents involved a man claiming to work for a housing association.
The suspect is white, aged 50 to 60, and around 6ft tall, with thick black hair and is well spoken.
Detective Constable Johnston said: "If anyone comes to your door that you are not expecting, check they have identification with them."
