One man has been sacked and three others have had their operating licences suspended after hidden cameras filmed alleged mistreatment of animals at a North Yorkshire slaughterhouse.
Footage captured by Animal Aid apparently shows sheep being kicked and punched at Bowood Lamb in Thirsk.
The Food Standards Agency (FSA) has begun an investigation, as Dan Johnson reports.
