Up to 40 people have been robbed at gunpoint during a church service in Dublin. The robbery happened at the Compassion Centre in Ballymun - a Christian outreach centre - at about noon yesterday. The congregation was forced to lie on the ground after being threatened with a sawn-off shotgun. The robber ordered them to empty their pockets, hand over bags, purses and mobile phones. He then fled the scene. Investigations are ongoing.
