Sir, – The sickening level of cruelty and abuse shown on film footage from Bowood halal slaughterhouse near Thirsk owned by father and son Robert and William Woodward will have horrified but maybe not surprised many readers.

This case raises many questions.

Why did the owners have no idea that this was taking place? If Animal Aid hadn't investigated this would still be going on. It makes a mockery of their claim that they take animal welfare seriously.

Why was no vet present for the duration of the filming.?

Why was only one person dismissed when the filming shows several people involved.The firm has admitted their guilt by suspending them.

Which shops and supermarkets and other outlets are doing business with this firm?

Bowood should have their licence revoked immediately and a thorough investigation carried out.

On the wider issue, slaughter without prior stunning should be banned immediately with no exceptions.
