The device was thrown into the window of a property in Melmount Villas shortly before 9pm yesterday (Monday). A person in the house threw it into a nearby field, where it was subsequently made safe by army technical officers.
“Those behind this viable device clearly had no regard for the lives of those people in the house,” said Mr Donnelly.
“Someone could have easily been seriously injured or killed by this incident. Despicable acts like these have no place in our society. This is now twice in the past month there have been incidents involving viable devices in Strabane and local people are sick of it.
“If anyone has any information on those behind this, I would urge them to contact the police immediately.”
