Three bogus workmen persuaded a Dundee woman to withdraw £900 from her bank.
Police Scotland are investigating an incident in Balunie Drive, Douglas, on Friday September 7.
A group of three men attended uninvited at an address, claiming that the building needed urgent repairs done to the roof.
They convinced the householder that this was so urgent that work needed done right away, and they needed money for materials.
The householder was then taken to a branch of her bank and withdrew £900, which she gave to the workmen.
A police statement said: “No work was undertaken, and in actual fact they had caused damage to her roof while ‘examining’ it.
“A neighbour alerted police to the incident, and the three men were subsequently traced and arrested driving away from the area. They have been released pending further enquiry, which is still ongoing.
“We would like to hear from anyone else in the Balunie Drive/general Douglas area of Dundee who has had a group of three men in a white van attend at their door and offer to do work of this nature.
“It should be pointed out that the men who attended at the victim’s door, as with many bogus workmen groups, were very plausible, appeared to be convincing, and even had leaflets advertising their services which looked real.
“No legitimate workman or firm will ask for large sums of money up front, and they absolutely will not take you to your bank to make sure you get the money.
“As a footnote – a legitimate local roofer has very kindly repaired the damage to the victim’s roof free of charge. He has asked not to be named, but we would like to pass on our gratitude all the same.
