DETECTIVES investigating a house fire in Freckleton, in which four siblings died, have arrested an 18-year-old man in connection with the investigation.
The teenager, from Lytham, has been arrested on suspicion of murder and is currently in custody.
Police can now confirm the fire was started inside a wardrobe in one of the bedrooms at the house in Lytham Road.
Detective Chief Inspector Neil Esseen said: “I can confirm this fire is now being treated as suspicious. We are following a number of lines of inquiry and have spoken with a number of people who were at the house on the night in question.
“However, I would still urge anybody who has any information which they believe could assist us with our investigation to come forward.”
