A fire on a Miller Construction site in Bristol is still burning after more than 78 hours.
Fire fighters are still on site tackling pockets of fire under the collapsed roof of the £16m police firearms training centre at Black Rock Quarry in Portishead, Bristol.
A spokeswoman for Avon Fire & Rescue said the fire service had scaled back its attendance to one fire engine but was still on site dealing with the areas that are still burning.
In a statement Avon Fire & Rescue said: “There are still a number of hotspots burning under the area where the roof has collapsed, although these are fewer than yesterday. Smoke levels in the area have been significantly reduced and although there is still some smoke, it is far less than in previous days.
“Work to gain access to the area under the collapsed roof using cutting equipment will continue today. This is an ongoing incident and the fire investigation will not begin until the fire is completely extinguished and it is deemed safe to enter the building.”
Yesterday fire fighters bought in specialist euqipment to cut holes in the wall in order to gain access to pockets of fire under the collapsed roof.
The fire was spotted by a passing police officer who raised the alarm at 4.37am on Tuesday.
An anarchist group claimed it set the building on fire but the police and fire services said they were keeping an “open mind” about the cause until they could carry out their investigations.
