GARDAI in Galway are searching for a man after an alleged sexual assault on a 19-year-old woman at the Spanish Arch in the city at about 9.30pm on Monday.
Officers sealed off an area around the Spanish Arch and a technical examination was carried out yesterday morning before it was re-opened to the public later in the day.
Gardai said they were seeking a man who is described only as wearing dark clothes and a hoodie.
"We are in the early stages of the investigation and are still trying to ascertain what happened," a garda spokesman confirmed.
Gardai have asked anybody who was in the area at the time or witnessed anything suspicious to telephone them at Mill Street garda station on 091-538000.
