The cab had been detached from the trailer containing crushed scrap cars, which was described as 'well alight' on fire crews' arrival.

The public are advised to avoid the area, and some businesses, such as Hitchin Library, have closed as a result.

Three fire engines from Hitchin and Stevenage remain in attendance along with an aerial ladder platform.

Police officers also attended to assist with road closures, which remain in place on Old Park Road westbound from A602 Parkway to West Hill.

Owain Jones, who lives opposite Hitchin Library, told the Comet that there had been a series of small explosions as flames ripped through the trailer: "I saw plumes of smoke outside and I saw a worried looking lorry driver uncoupling the lorry engine from the container.

"It was pretty dramatic, as you can see. There have been a couple of small explosions that made passers by jump and were of a concern to myself and my next-door-neighbour.

"The fumes were pretty toxic and we've been told it was scrap cars bundled up. The fire engines have had to fill the container with water as it's still smouldering three hours later."
