Officers seized more than 1,000 cannabis plants as they disassembled an "extremely professional" set-up inside a two-storey building in Lenwade, between Norwich and Fakenham.

Following the police operation, which started on Wednesday, nine people were arrested and have been charged with producing a quantity of cannabis, a controlled drug of class B.

Many of the gang members have already appeared in court but two of them were at Norwich Magistrates Court on Monday (July 22).

A 15-year-old boy who cannot be named for legal reasons has had his case formally sent to Norwich Crown Court on August 15.

He has been remanded in secure accommodation in the meantime.

Also appearing before magistrates on Monday was Kien Le, 26, of no fixed address.

But he had his case adjourned as there was no interpreter available.

Others who have already appeared include:
