This is the moment a man was arrested over the devastating wildfire in Avila that has burned through more than 9,000 hectares of land.

Investigators believe the blaze in Burgohondo was sparked by a single spark produced by heavy machinery being used during forestry work.

The fire remains at Level 3, Spain’s highest classification, meaning it has been declared a national emergency.

The investigation was launched by the Guardia Civil’s environmental unit (SEPRONA), working alongside specialists from Castilla y Leon’s Forest Fire Investigation Brigade (BIIF).

Following a forensic examination of the scene, investigators concluded there was evidence linking the origin of the fire to the machinery being operated in the forest.

According to the Guardia Civil, the work was being carried out despite a regional ban on using machinery capable of generating sparks or flames in woodland due to the extreme wildfire risk.

Investigators also allege those responsible did not have the necessary administrative authorisation to carry out the work and had failed to comply with regional fire prevention regulations requiring such machinery to carry firefighting equipment.

Two suspects are being investigated for alleged forest fire offences and crimes against natural resources and the environment.

The Guardia Civil added that prosecutors are also considering aggravating factors because the fire threatened populated areas and caused serious damage to local ecosystems.

Police said the case file, together with expert reports compiled during the investigation, will now be sent to the court and the Provincial Prosecutor’s Office in Avila.
