Vicious sex attack on teenage girl
She had just left a group of friends to continue a short journey alone and was near her own home when she was set upon.
The teen shouted for help as she struggled with the man, who punched her repeatedly in the nose and also left her with a black eye before making an escape on foot.
One garda officer said today: "The girl put up a fight and we are seeking help from anybody who was in the Monastery Road area around that time and might have witnessed either the assault or saw the attacker running from the scene.
"This was a very violent incident which left the victim with severe injuries and in a very distressed state."
The culprit is described as being a white male, six foot in height with dark hair.
Detectives are also examining footage taken from CCTV cameras in the area in an effort to identify the thug. It is understood that gardai are also using a specialised computer system known as ViCLAS to determine if last Sunday's crime is linked to other similar crimes.
ViCLAS, the Violent Crime Linkage Analysis System, is a computer system developed by the Royal Canadian Mounted Police in the early 1990s to compare different crimes for similarities. Local detectives have provided information to specialist officers in Harcourt Square Garda Station, who input the data into ViCLAS.
While sex attacks on Junior Cert results night are extremely rare, a 16-year-old girl was brutally assaulted after leaving a youth disco at Carraig Springs Hotel, Crosskeys, Co Cavan back in 2002.
Anyone with any information about last weekend's assault is asked to contact Clondalkin Garda station at 01-6667640.
