Police are treating the fire at industrial packaging recycler Tradpak as arson and are appealing for more information.
The fire at an industrial estate in Armley, Leeds on Easter Monday destroyed part of the Tradpak premises, and spread to neighbouring Hazel Products. It is estimated to have caused damage to the businesses worth £6-7m. No one was hurt in the blaze.
More than 100 firefighters tackled the blaze and stopped the fire spreading further.
Detective Inspector Mark Swift, of Leeds District CID, said that the destruction from the fire and the massive amount of water used at the scene made the forensic investigation challenging.
“We worked closely with specialist fire investigators and established that the fire had been started deliberately and as such we are investigating this incident as arson,” he said.
The police want to hear from anyone who saw anyone in the area or who has information that could help the investigation.
In a statement at the beginning of the month Tradpak said that while the whole of the yard, IBC processing facilities and stock were completely destroyed, the offices, some operating areas and most of our transport fleet were undamaged. The firm said that they were well underway to getting back to full production.
