A pipe bomb has been thrown into a house in Dungannon, County Tyrone.
It happened at Windmill Court shortly before 0100 BST on Sunday. It is believed a window was smashed and the pipe bomb thrown inside, causing substantial damage to the kitchen.
No-one was in the house at the time, and no injuries have been reported.
About 50 people living nearby were moved from their homes to a community centre for almost five hours while an Army bomb team examined the area.
The man who lived at the house is believed to have been at home with two friends until less than an hour before the attack.
It is understood he has gone to stay with relatives.
Police have appealed for anyone with information about the incident to come forward.
