A second home in Finglas was the subject of a suspected petrol bomb on Saturday night.
It comes after an attack during the early hours of Saturday morning on an innocent family member of James Whelan, the 29-year-old father-of-one who was killed last month. His mother and another person were in the house at the time of the attack, Dublin Live understands.
Neither or them have any involvement in crime, nor does anyone who lives in the house.
