IRISH police want killer Patrick Rae extradited from Scotland to face allegations of sexual assault.
Rae is serving 20 years for raping and murdering Dundee mother-of-three Mary McLaren in February 2010.
But it has now emerged that Irish detectives want him to stand trial for a sex attack on a 30-year-old woman in Portmarnock, near Dublin, in April 2008.
Rae, 41, was on the run from the Gardaí when he managed to escape to Scotland.
He had 13 previous convictions – including rape and serious assault – in the Irish Republic.
A Garda insider said the force was intent on bringing Rae to justice.
He said: “He’s a nasty piece of work. He’ll be banged up for 15 years if he’s found guilty.”
Sergeant Tony Conaughton from the Gardaí said last night: “We do not discuss named individuals.”
A spokesman for the Scottish Prison Service also declined to confirm if Rae is to be sent back to Ireland.
He said: “We do not comment on individual prisoners.”
A spokesperson for the Crown Office said they had not yet received an extradition warrant for Rae.
During the trial which took place last June, jurors heard how Rae was able to flee from Ireland, using the slightly different surname of Rea.
Despite having an outstanding warrant for arrest, he did not alert Irish authorities of his change of address which he was required to do.
And on arrival, the serial rapist settled in a caravan site in Aberdeen, before moving to Arbroath with his Scottish girlfriend.
While living in Arbroath, he travelled to Dundee for a night out where he met mother-of-three Mary McLaren in a night club.
Rae was caught on CCTV dancing with the 34-year-old before he raped and strangled her just hours later.
Her body was found two weeks later on March 10, 2010, hidden in the undergrowth of the Ladywell roundabout inDundee.
The McLaren family declined to comment on the development when asked last night.
