A 31 year-old man from Abertillery was sentenced yesterday to six years in prison for setting fire to the Real Crisps factory in Crumlin in 2012.
Speaking after the case, South Wales Fire & Rescue said arson is 'unacceptable.'
Currently 78% of all fires attended by South Wales Fire and Rescue Service are started deliberately which is completely unacceptable.
Arson is a serious crime that has an impact on the whole community. The South Wales Fire and Rescue Service Fire Crime Unit will continue to work with the Police and its partners to bring arsonists to justice.
We also urge members of the public to help us look after their communities and the safety of their families by reporting any individuals they believe are involved with arson activities.
