Arrest over Real IRA man Alan Ryan's murder in Dublin

Alan Ryan was shot dead at Grange Lodge Avenue in Clongriffin

A man has been arrested by police investigating the murder of a Real IRA man in Dublin earlier this week.

Alan Ryan, 32, was shot several times at Grange Lodge Avenue in Clongriffin on Monday afternoon. A second man was also shot and sustained leg injuries.

A man in his late 40s is being questioned at a Garda station in north Dublin.

In 2000, Ryan had been jailed over the discovery of a Real IRA training camp at Stamullen, County Meath.

RTE crime correspondent Paul Reynolds said the Dubliner was "very well known in criminal and republican circles both north and south of the border".
