A community alert has been issued following suspicious activity in the Termon area this afternoon.
It follows a number of incidents in which a white van was spotted at a number of houses.
Two occupants, a man and a woman, were then seen trying to access the backs of houses.
When approached the duo asked people if they had any scrap metal for sale.
The van is a new 141 DL van and is white in colour.
Anybody who spots the van should report its movements to local Gardai.
