A Suffolk recycling centre fire is being investigated by police after safety measures failed to stop its second fire in the space of a month.

The site in Great Blakenham says it is "trying to understand why the fire was bigger than the first", and has put in place a 24-hour fire and security patrol.

Crews from fire stations across Suffolk attended the Sackers scrap metal and waste recycling centre after being called at 3am on Saturday.

Suffolk Police say their investigations are ongoing and the fire is being treated as "unexplained".

The fire service sent a dozen crews to the centre and stayed on-site until the next morning.

According to Suffolk Fire and Rescue Service, the fire measured around 40 metres by 100 metres.

Nobody is believed to have been injured.

A spokesperson from Sackers praised the work of the fire service in keeping everyone safe and some of their staff, who came out to help.

They said: "We still do not know what caused the fire, and it is with the police to investigate. Our robust fire prevention plan, which is approved by the Environment Agency, came in to play as it did last time.

"But we are trying to understand why the fire was bigger than the first, with the same measures in place.

"The explanation for this hasn’t been ascertained but when we have more information on what caused the fire, it might provide more clarity and in turn, offer further improvements to future-proofing our business from these terrible incidents.

"Until then, we are unable to give further information relating to this fire. However, we have implemented, with immediate effect, 24-hour fire and security patrol office on site, and are exploring new technology to up the ante even further. 

"We are meeting with the representatives of the local residents committee to discuss any concerns they have. We have had lots of businesses reaching out to show their support and offer help, all of which we are incredibly grateful for."
