A fire at a bar on Dawson Street in Dublin is being treated as arson. It caused the city centre route to be closed off earlier this morning after the blaze broke out at cocktail bar Peruke and Periwig shortly before 5am. Dawson Street was shut in both directions, while the luas was suspended between St Stephens Green and Dominic, as emergency services put out the fire. The route has since reopened to traffic and trams are back running. Image: Google street viewFollow @98FM on Twitter for the latest Dublin news.
