Mr Moffitt’s body was found in a house in Cartron Heights at around 8.30pm and had suffered what Gardai described as “significant bodily injuries”.

Be very careful with a person who does not share a recent face photo with you,” they said in a statement on Tuesday. “Ask for the manipulation of social media … Be careful with new accounts with a low number of followers and few posts.
