The cubicles, some of which had not been emptied, were taken from Ludlow Autograss Club in Pencombe, Herefordshire on Sunday.

It is believed that the thieves cut a padlock the night following a motor racing event and loaded up their Ford Transit van with the cubicles.

Owned by a small family business, the toilets were bought only last year at a cost of around £40,000.

A West Mercia Police spokesperson said: “On Sunday we received a report of the theft of 35 portable toilets from a field in Pencombe, Herefordshire. Enquiries are ongoing.”
