Gardai are appealing for witnesses following an alleged sex assault on a woman in Dublin.

It happened in the early hours of Sunday morning at Mount Argus Road in Harold's Cross.

A man reportedly forced a woman against a car, when he was interrupted by an approaching couple.

The suspect is described as being approximately 6 feet tall, with broad shoulders, black hair and a beard - and is able to speak in Spanish.

Gardai are appealing for witnesses to contact them - in particular the couple who approached the pair between 5am and 5.30am.
