DNA profiling is being used to narrow down potential suspects in an investigation into an alleged rape in Dublin.
Gardaí are understood to have chosen around 100 men for screening - because their cars match the suspect's vehicle.
The Irish Times says the attack was reported by a woman after a night out on December 11th 2015.
It's the first time Gardaí will conduct such an operation since the introduction of the country's DNA database over 12 months ago.
