Gardaí at Store Street sourced CCTV footage and Murphy could be seen putting on a pair of gloves before jogging after the first victim and walking closely behind her.

His probation officers and former prison officers identified him from the footage. He was arrested and questioned, but left the country after he was released.

He was found three years later in the UK and extradited last year.

At Dublin Circuit Criminal Court, Judge Melanie Greally said there was "every reason to conclude" that Murphy intended to engage in "very serious acts of sexual violence" but for the bravery and actions of the victims.

She said the offending was aggravated by the fact he had recently been released from prison for the false imprisonment of a female.

The judge sentenced him to six years in jail with a further four years of post-release supervision.
