Burglary figures dropped 50% after arrest of gang
An extended family gang carried out more than 250 burglaries during an 11-month crime spree in the East of England, police said.
The 12 men stole jewellery, cash, cars and guns worth a total of £2m from homes and businesses across five counties in 2017.
The extent of the enterprise can now be reported - after three of them were convicted by a jury at Norwich Crown Court on Wednesday.
Det Insp Craig Harrison, from Cambridgeshire police, said the men considered crime "just a way of life".
The crimes were committed in Cambridgeshire, Norfolk, Suffolk, Essex and Bedfordshire.
