Gardai have said that other matters may come before the court in relation to a serving member of the Defence Forces already charged with having explosives.
Private Mark Cassidy, 29, appeared at Letterkenny District Court this morning.
No bail was sought by Cassidy’s solicitor, Eugene Burns, and the case has been put back until next Monday.
Garda Inspector David Kelly said directions had been received from the Director of Public Prosecutions but said that “there may be other matters brought before the court.
He also asked for Cassidy’s legal team to give Gardai time to carry out the relevant checks on people being put forward as independent sureties.
Cassidy had been brought to a special sitting of Letterkenny District Court last Thursday amidst tight security.
Cassidy, of Grianan Vale, Ballyederowen, Burnfoot, faces two charges of possessing explosives at the same address on Monday February 19th.
He is charged with having an explosive substance and also possessing 87 twelve gauge shotgun cartiridges.
Detective Garda Michael Carroll told that sitting of the court that he arrested him on Tuesday, February 18th and put the two charges to Cassidy but the accused made no reply.
Garda Inspector Michael Harrison had said he was objecting to bail because of the seriousness of the offences and because Cassidy had no permanent address in the Republic.
