According to the Interior Ministry, the suspects had been watched for two months, with photos of the transactions taken by tiny cameras hidden in the lapels of agents disguised as students, pensioners and workers.
Prema Ministarstvu unutrašnjih poslova, sumnjivci su praćeni dva mjeseca, a fotografije transakcija snimane su malenim kamerama skrivenim u kragnama agenata prerušenih kao studenti, umirovljenici i radnici.
