Gardai in Dublin have arrested a man in connection with an attempted armed robbery at a post office in Baldoyle.

Just before 1 o'clock this afternoon a number of men entered the post office and threatened staff - at least one of them was carrying a firearm.

The men left the premises without any money and got into a waiting car - believed to be a 08 OY black BMW 1 series which was last seen on Station Road in Portmarnock.

No one was injured in the incident and no shots were fired.

A 43 year old was arrested a short time later in Portmarnock - he's being detained at Coolock Garda station under Section 4 of the Criminal Justice Act.

Any witnesses to the incident are being asked to come forward.
