Two 14-year-old boys have been arrested in connection with the fire, which broke out on Thursday night.
Demolition work to flatten the remains of the burned-out structure has been underway today, with nearby residents being evacuated from their homes.
Detectives investigating a fire at a former Preston nightclub have made a third arrest.
