An investigation has been launched into the cause of a raging inferno broke out at a large warehouse in the Spen Valley.

Residents living nearby reported hearing 'explosions' from within the intense blaze as numerous calls were made to Cleckheaton fire station.

Fire crews from across West Yorkshire were scrambled to the scene in Wormald Street, in Millbridge, between Heckmondwike and Liversedge.

Large plumes of smoke could be seen for some distance, rising into the sky above the burning industrial building.

The blaze raged on for more than four hours, with fire chiefs warning residents to keep their windows and doors closed.

The fire started at around 7pm and it was not until 11.30pm that the fire service announced it was 'now under control with crews being scaled back.'

Nobody was inside the building, a spokesperson for Cleckheaton fire station confirmed.

At the height of the blaze, a dozen fire engines were at the scene, assisted by two aerial ladder appliances. Crews from Bradford, Odsal and Cleckheaton were among those scrambled to the incident.

A spokesperson for West Yorkshire Fire & Rescue Service confirmed the incident was 'make pumps 12' - but this had been reduced to five fire engines and one aerial appliance shortly before midnight.

Speaking on Wednesday morning, a spokesperson for Cleckheaton fire station confirmed an investigation into the cause of the fire remains ongoing.
