GARDAÍ ARRESTED A man in his 40s in Dublin this morning and TheJournal.ie understands that the arrest was in connection with security operations surrounding the visit of US president Barack Obama to Ireland on 23 May.

Gardaí from the Special Detective Unit investigating threats to kill or cause harm searched a dwelling in Dublin 1 and arrested a male in his 40s.

He is being held at Store Street Garda Station under section 30 of the Offences against the State Act.

RTÉ reports this evening that the man is 44-years-old and is described as an “alleged al-Qaeda sympathiser” who has been known to gardaí and interviewed a number of times in the past.

Separately, the Evening Herald reports that a feared Real IRA boss was one of three men arrested by gardaí this morning in a major clampdown against dissident republicans ahead of the visit of Queen Elizabeth next week.

The 31-year-old man was arrested at a house in Donaghmede in north Dublin. Two other men, aged 20 and 29 were also arrested as part of the operation.

Gardaí confirmed this evening that the three men will appear at the Dublin Courts of Criminal Justice tomorrow morning.
