Police in Dungannon are warning about rogue traders.
They're currently investigating a report from a resident who expressed concern about possible bogus callers earlier this month.
They believe these callers may have been attempting to carry out work on a house.
Police want all householders, particularly the more vulnerable, to have the confidence to refuse services they do not want.
Householders are reminded to check callers' identification.
"We want to empower residents to discourage those unofficial traders who may overcharge an unsuspecting householder for poor quality work or work that is never completed at all. Rogue trading and its links to burglary can have a significant impact on the vulnerable and elderly within our communities," explains Constable Mark Baxter.
"Often rogue doorstep traders target the most vulnerable in our society. If you would like crime prevention advice please speak to the Crime Prevention Officer, or if you have any concerns about callers that have come to your door, please contact police on the non-emergency number 101," he adds.
