The operation to detect the presence of preparing the bombs in the vicinity, which were later identified using a voucher system then colored numbered. Once the addresses identified, teams of SAS took over was arrested several manufacturers of bombs, without any injuries or killed. The reality sometimes fiction, and this secret operation to stamp.
