Investigations continue after more than 50 firefighters tackled a huge blaze at a former government building near Blackpool over the weekend.
The fire at the old Department of Work and Pensions site at Warbreck Hill Road in Bispham was spotted at about 11:30pm on Friday.
Firefighters brought the blaze at the large site under control and were damping down through the weekend.
Firefighters are still at the incident ground and are monitoring hotspots which are occasionally flaring up due to windy weather conditions.
Crews remained at the scene overnight into Monday morning, with a consistent presence at the incident ground overnight whilst damping down and monitoring is taking place.
The incident has now been reduced to three appliances and the aerial ladder platform.
