A lorry caught fire at the A4500 truckstop at around 4am this morning.

The fire destroyed three lorries but is now under control, Northamptonshire Fire and Rescue says.

A fire service spokesman said the smoke, which could be seen billowing into the skies from across Northampton, had initially caused problems.

He said: "At the height of the fire, residents in the Harpole area were warned to keep their windows and doors closed because of the large plume.

"We've got it under control now, so that advice is not in place any longer."

Red Lion is set to remain open today while firefighters dampen the flames.

At just before 9am, the number of crews was due to be scaled back to just one.
