A man is due in court in Dublin this morning in relation to a firearms seizure in Dublin earlier this year.
The seizure took place at an industrial estate in Baldonnel on January 24th.
Gardaí seized 15 firearms and 1,300 rounds of ammunition during the operation, as well as a 'substantial amount' of cash.
A 28-year-old man was arrested in connection with the investigation on Sunday, and was detained at a Garda station in west Dublin.
He is due before Blanchardstown District Court this morning, charged in connection with the seizure.
Gardaí say he is the fourth person charged in connection with the case, with three other men currently before the courts.
