At this stage we believe this fire may have been stated deliberately.
I am keen to hear from anyone who may have seen anything suspicious, such as someone outside the front of the property, before the fire broke out. I would also ask anyone living nearby who has experienced a fire recently that they may not have reported to come forward.
Currently we are treating this as arson and a man and a woman remain in a life-threatening condition in hospital. Their injuries are severe and I would welcome information from the public that will help us uncover exactly what has happened."
