UK: Halal Poultry Plant Workers Not Kosher

Immigration officers have arrested 27 workers at a halal chicken processing factory in Preston. It is understood that they are being held on suspicion of offences including illegal entry into the UK.

The number of people arrested accounts for about half of the Gafoor Foods-owned plant's workforce. The workers are from countries including India, Pakistan, Afghanistan, Belarus, Iraq and Jordan.

Halal: permissible under Islamic law.

So presumably working as an illegal immigrant IS permissible under Islamic law?
