Two Irish Defence Forces personnel arrested by armed Gardai are being quizzed about alleged links to a dissident republican group in Derry, Derry Daily has learned.
The two serving soldiers, arrested in Donegal earlier today, are also being questioned about the discovery of a pipe bomb in Burnfoot, Inishowen yesterday evening.
It is understood the Defence Forces have been assisting Gardai with their investigations in recent weeks, amid allegations the two men have dissident contacts on this side of the Border.
The pipe bomb investigation is also linked to the discovery of a similar device at Letterkenny Garda Station last year.
Forensic experts are examining the device found yesterday for similarities to that bomb.
It is understood the arrests came today as part of fast-moving Garda investigation.
