The DPP has ruled that a gangster who was cleared of the murder of Romanian teenager Marioara Rostas will not face additional charges in relation to a number of firearms seizures which had been linked to him.
Alan Wilson (35), of New Street Gardens, Dublin, is one of the capital's most notorious criminals, but he was cleared of murder at a trial during the summer after a jury was not convinced by the evidence of state supergrass Fergus O'Hanlon.
Convicted criminal O'Hanlon also provided gardai with information that allowed officers to make six different firearms seizures resulting in 11 guns being discovered as well as hundreds of rounds of ammunition.
Investigations later established that one of the handguns had been used in a gangland murder seven years ago.
Weapons were found at several locations including under the concrete patio of a property in the Crumlin area. Others were buried in Bushy Park, Terenure.
The deadly arsenal included a Magnum handgun, several sawn-off shotguns and .22 rifles and assorted ammunition.
Specialist officers carried out detailed tests on the 11 firearms that were found.
Sources say that gardai obtained evidence that linked some of the weapons to Wilson through DNA and fingerprint analysis.
Wilson is currently serving a seven-year sentence in relation to an incident in which he attacked a man with a meat cleaver after breaking into his home in Blanchardstown. Gardai later found firearms residue on his clothing.
After Wilson's acquittal for murder earlier this year, the DPP has decided he will not face trial for the firearms offences.
