Elderly people in the Lambhill and Summerston areas of the city were targeted and robbed by the thief within a week.
The first incident happened on June 18 in Summerston, when the robber entered the property of a 90-year-old man.
He managed to gain access by saying he needed to check the gas and electricity at the property.
After distracting the elderly resident, the thief stole a small amount of cash and ran off. The suspect then targeted a 78-year-old man, at a property in Lambhill.
Again, he claimed to be a workman who needed access to check the gas and electricity and escaped with a sum of money.
