THREE more men have been arrested in connection with a huge drugs factory discovered in Theydon Bois, as a fourth man prepares to appear in court tomorrow (Monday).

Hai Van Doan, 27, of no fixed address, will face Harlow magistrates after being charged with "being concerned in the production of cannabis" following the seizure of 5,000 of the plants in a warehouse on Friday.

Police say the drugs have a street value of more than £1million.

The trio arrested by officers have not been named, but include a 54-year-old man from Wickford, a 35-year-old from Romford and a 44-year-old from Ingatestone.

They are currently being quizzed by police.

Officers said yesterday that the factory was one of the largest of its kind ever discovered in Essex.
