Gardai investigating the 2010 murder of two men who were gunned down outside a petrol station made an arrest during the summer, the Dublin coroner has heard.
Glen Murphy (19) and Mark Noonan (23) died when gunmen opened fire as they stopped at a petrol station outside the Tesco Clearwater Shopping Centre in Finglas on November 23, 2010.
They were there to buy cigarettes when a dark BMW pulled up and the gunmen opened fire.
Mr Noonan was hit in the back of the head while Mr Murphy was shot in the head and stomach as he scrambled to get away from his killers.
Neither victim was involved in organised crime and gardai believe the murders may have been a case of mistaken identity.
The inquest into their deaths was opened in March 2011 and has been adjourned on several occasions since to allow gardai to continue with their investigation.
Updating the Dublin coroner on progress in the case, Det Insp Colm Murphy said the investigation remains active.
"There was a recent arrest during the summer and a number of inquiries made abroad with members of An Garda Siochana travelling abroad," he said, requesting a further adjournment of the inquest.
Coroner Dr Brian Farrell told the families that because there are "live issues being investigated", he is not in a position to go ahead with the inquest.
He adjourned the matter for further mention on June 5 next year.
