A second man has been arrested in connection with the seizure of a firearm and €200,000 euro worth of drugs in Dublin.

The man, who's in his 20s, was arrested last night in Tallaght.

He's being questioned about the discovery of a sawn-off shotgun and ammo, aswell as heroin and cannabis, in a car in Jobstown last Thursday.

He is currently being detained under the provisions of Section 30 of the Offences Against the State Act at Tallaght garda station.

A teenage boy was arrested immediately after the seizure, but he has since been released without charge - pending a file being sent to the Director of Public Prosecutions.

The garda investigation is ongoing.
