Gardaí have seized a gun and ammunition in Dublin City Centre.

It happened after gardaí on patrol intervened in a fight involving a “number of individuals” on Abbey Street shortly after midnight last night.

Investigators said they saw a man throwing something into a bin on Liffey Street and, after gardaí searched it, they found a suspected firearm with ammunition.

A man in his 30s and a woman in her 20s were arrested at the scene ad are being held at Store Street Garda Station.

The gun has been sent to for analysis by the Ballistics Section.

The investigation is continuing.
