A Letchworth man has been charged with 'being concerned with cannabis cultivation' amid a widespread Herts Police operation that led to more than 20 arrested.

In Hertfordshire more than 30 warrants were conducted with 27 people arrested, of which 10 have been charged, and 3249 cannabis plants were seized. 

This led to Shadrach Allen, aged 42, of Cade Close, Letchworth, charged with being concerned with cannabis cultivation during officers' month-long operation to combat cannabis cultivation. 

Herts Police's operation was part of a wider action by forces across England and Wales, who conducted activities targeting cannabis production by organised crime groups - that saw more than 1,000 warrants exercised during June. 

Herts' Local Policing Command teams were supported by the Operational Intelligence Team, Operational Support Group and local crime and safer neighbourhood units to carry out the warrants.
