Man held in connection with Down bomb attack

Police in the North have arrested a man in connection with a bomb attack in Co. Down earlier this year.

A dissident republican group claimed responsibility for the explosion outside MI5's headquarters in Holywood in April, minutes after policing and justice powers were devolved from Westminster to Stormont.

The 45-year-old man was arrested in north Belfast this morning and being questioned at Antrim Police Station.

A number of arrests have been made but so far no-one has been charged.
