The incident happened on Queensway at around 9pm on Friday October 31 when an out building was set on fire.
Police and the Fire Service were on scene quickly and the fire was brought under control before it caused any significant damage.
One witness has come forward stating that they saw four teenagers dressed in dark clothing near to the scene prior to the attack.
The incident followed another arson in the area on October 29 when a car was set alight on Butler's Meadow.
The estate has seen a staggering 16 arson attacks since July.
Inspector Sue Swift said: "Somebody in the local community must know who is behind these fires. The only way we can put a stop to it is by catching the people responsible.
"I would like to reassure residents that CID are investigating these fires and would urge people not to take matters into their own hands. Our Neighbourhood Policing Teams are working closely with the local community and are available for people to talk to. We are also working closely with Lancashire Fire and Rescue and Fylde Borough Council to try to prevent future attacks.
"I would like to remind residents in the area to be vigilant and to ensure that they lock their garages and sheds and secure their properties."
