A woman who was arrested and questioned about the murder of Real IRA terror chief Alan Ryan was yesterday dramatically rearrested over a double murder.
Last night, gardai were quizzing the woman about the separate murders of cousins Glen Murphy (19) and Mark Noonan (23) who were gunned down on the forecourt of the Tesco Clearwater filling station in Dublin, on November 23, 2010.
The Kilbarrack woman, who is the girlfriend of a notorious gangland getaway driver, had been held at Coolock Garda Station about the Ryan murder after her arrest for shoplifting in a north Dublin store.
It has emerged that Coolock gardai finished questioning her about Ryan's murder at around 5pm yesterday, but she was then immediately rearrested by officers from Finglas Garda Station who believe that she may have information about the sickening double murder almost four years ago in which the two cousins were shot dead in a case of mistaken identity.
Sources have revealed that the Kilbarrack woman, who now lives in Northern Ireland, is suspected of being a driver in car that was in a convoy of vehicles that left Dublin for the North after Alan Ryan's murder on the afternoon of September 3, 2012.
It is common for organised criminals to travel in convoy before and after serious crimes so that they can let their associates know of the imminent presence of police or gangland enemies.
After being questioned about this and other events about the murder of Ryan, the woman was released without charge but was quickly rearrested.
Sources say that gardai were last night questioning her about her activities and the movements of her gangster boyfriend on the night of Tuesday, November 23, 2010.
It was on this night at 11.40pm that Dubliners Glen Murphy (20), of O'Devaney Gardens, North Circular Road, and Mark Noonan (23), Drumalee, North Circular Road, were shot dead at the service station in Finglas.
The two young men had gone to the filling station to buy sweets and cigarettes.
Gardai believe they were followed by a gang using a tracking device which had mistakenly been put in the car they were in.
Sources say Mr Noonan's Toyota Avensis car was very similar to a car which was driven by the intended targets - two feared Coolock drug dealers who survived several attempts on their lives between 2008 and 2010.
The intended targets were in a bitter feud with a rival mob.
Like Ryan's murder, gardai believe the double murder of the innocent cousins was carried out by the 'Mr Big' drugs gang.
And sources say that detectives believe that the boyfriend of the woman who was in garda custody last night was in the killer's car when the savage double shooting occurred in November 2010.
It is not known what the woman knows about the double murder but sources say that it is "improbable" that she was present on the night of it.
Her boyfriend, who is based in Northern Ireland, is known as one of the best getaway drivers in the capital's criminal underworld.
