“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.”
