A man has been arrested in connection with the fire at a fireworks warehouse on Thursday night.
Two people remain missing, with four more injured, including two taken to hospital for treatment for serious burns and smoke inhalation, after the fire that broke out at SP Fireworks around 17:20 GMT.
It took 50 firefighters to bring the blaze under control, with a team of firefighters remaining at the scene overnight.
Police closed a number of roads around the Baswich Industrial Estate and businesses and homes were evacuated.
Supt Ian Coxhead confirmed that a 53-year-old man had been arrested in connection with the blaze:
“We have a great deal of sensitive and challenging work to complete in order to allow us to establish the cause of the explosion and following fire. We understand the unit was storing a significant volume of fireworks which appear to have been completely destroyed during the blaze last night. This makes the ongoing examination of the scene particularly challenging and we expect to be at the scene for some time. We can confirm a 53-year-old male has been arrested in connection with the incident.
“We understand that of the one of people taken to hospital last night is in a poorly condition, whilst the second is stable after receiving treatment.”
In a statement, the Staffordshire Police said:
“This morning the focus of the joint police and fire investigation will be to recover any potential evidence from the wider scene and assess the safety of the remaining structure in order to progress the search and investigation. This is part of the work to establish the cause and we can’t speculate about how this explosion occurred until the forensic examination is completed.”
