Two adults and three children escaped injury when a pipe bomb exploded near a house in Co Londonderry early on Tuesday.
A number of windows at the back of the property at Castle Park in Tobermore were damaged in the incident around 1am.
Police said a house in Calmore Park directly behind Castle Park was also damaged in the incident. The occupants of that property also escaped injury.
UUP MLA for the area Sandra Overend condemned those responsible for the attack as “reckless”.
“Nothing can justify placing an explosive device at a house, especially one with children inside, and such actions must be condemned by everyone,” she said.
“Somebody out there knows who is responsible for this terrible act, and I would appeal to them to pass any information they have to the PSNI so that the culprits can be brought before the courts.”
