An illegal migrant who tended a £1.5million cannabis farm above a luxury restaurant has been jailed for three years.

Le Thanh Long, 23, worked as a gardener at an industrial-scale grow house as oblivious guests continued to 'enjoy fine dining' just a few floors below at the Casa Brighouse hotel and restaurant on Elland Road, Bradford.

When police raided the venue on August 5 last year, they discovered more than 1,700 cannabis plants spread across 13 grow rooms on the upper floors of the restaurant.

The crop could have been worth around £499,100 in wholesale value and £1,426,000 at street value, while there was also evidence of an 'obvious previous cannabis harvest', Bradford Crown Court heard.

Cops uncovered the cannabis farm after realising the venue's electricity supply had been bypassed and reconnected from the street.
