Three men have been arrested following the discovery of weapons and drugs worth an estimated €4m in Dublin.

Following a search in the Ballyfermot Parade area of Dublin, gardaí seized stun guns, a sawn-off shotgun and a semi-automatic pistol alongside a large quantity of cannabis and heroin.

Gardaí said a range of drug paraphernalia – including a vacuum packing machine and cash-counting machine – was also uncovered.

The search was undertaken as part of ongoing investigations targeting organised crime in the capital.

The three men were arrested during follow-up searches in the south inner city.

The men – aged 39, 44 and 46 – are being held at Clondalkin and Ballyfermot Garda Stations.
