Detective Inspector Kerry Brennan said: “At approximately 7.30 am, Northern Ireland Fire and Rescue Service reported a fire at a unoccupied property in the Herbert Street area of north Belfast.
“Police attended along with the NIFRS, who have ruled the blaze to be deliberate and so we are treating it as arson.
“A 33 year old man was arrested on suspicion of arson and currently remains in police custody.
“Anyone with information in relation to this incident should contact detectives on 101 quoting reference number 565 of 01/09/19.”
