The force has launched a joint investigation into how the blaze started with Lancashire Fire and Rescue Service.
A man, 19, a woman,18, and a 17-year-old girl have been held on suspicion of criminal damage (arson not endangering life) and have since been bailed. A 19-year-old woman has been arrested on suspicion of the same offence and remains in custody.
