The RUC in Derry is investigating an incident in which a gang of armed and masked men smashed their way into a house in the Creggan area of the city on Tuesday night.
The incident, which happened just after 9.30 p.m., involved 15 masked men armed with two handguns and clubs.
They drove up to the house at Iniscairn Crescent in three cars and kicked in the front door of the house, which was occupied by a couple and their three young children.
