FIRE crews were called to the 13th arson attack in just six months at a block of flats.
The bin chute in the waste compound of flats on All Hallows Road, Bispham, was set alight on Tuesday morning.
Two fire engines were called to the incident at around 3.31am.
Mick Spencer, watch manager at Bispham fire station, said: “This is the 13th such fire since March.
“It is very worrying for the residents.
“Someone must know something.”
Severe fire damage was caused to one wheelie bin, and smoke damage to the compound.
But fire crews said there is a risk of smoke spreading to surrounding flats.
Mr Spencer added: “It’s a drain on resources when someone starts fires deliberately.
“While we’re dealing with this we can’t attend other incidents, we can’t be in two places at once.”
The fire service is now working with the police and Blackpool Coastal Housing to secure the bin compounds to prevent future attacks.
