POLICE are investigating an arson attack after a van was discovered on fire in a yard at a rabbit farm.

Firefighters attended Highgate Farm in Normanby-by-Spital, near Market Rasen, at about 2.20am on Monday.

A white Mercedes Sprinter van was found ablaze and the vehicle was totally destroyed.

Police are investigating it as arson at the premises, which supplies rabbits to Huntingdon Life Sciences' Cambridgeshire lab.

As reported in the Echo, officers from five police forces converged on the farm in September last year, where hundreds of animal rights protestors staged a demonstration.

Owner Geoff Douglas pointed out the business's lawful activity is regulated by the Home Office.

Anyone with any information on the arson, or who saw anything suspicious in the area between midnight and the time the fire was discovered, should call police on 0300 1110300.
