Boiler-suited Gards and sniffer dogs are combing fields around Killygordon in the Finn Valley area.
It is in response to the arrests of three men earlier today in Co Donegal in connection with the discovery of a bomb under a policeman’s car in Derry this morning.
The three suspects were arrested along the border after crossing from the North.
They have been taken for interview to both Letterkenny and Milford Garda stations but no other details are available at present.
They are being questioned under the Offences Against the State Act.Tags:
