The cause of the Pond Post Office fire has been revealed as it undergoes refurbishment.

Hertfordshire Fire and Rescue Service has told the Watford Observer that the blaze was due to an accidental electrical fire.

It broke out at the site in The Parade, Watford, on April 7 at around 4.20am, with flames being dampened down and completely out by 6.20am.
