The Financial Crimes Squad (SDOE) detected more than 8,500 irregularities in the checks that it performed during the first half of this year, as the government steps up measures against tax dodgers to save the budget from possible derailment over the next few months. SDOE conducted 23,256 checks in the six months ending June and found that 8,545 infringements had been committed by businesses, with the main culprits being transport companies and travel agents. Businesses offering entertainment and cultural activities were next on the guilty list, followed by timber firms. SDOE, however, will make way for the Special Investigation Service (SIS) on Monday, as the government axes the previous service in a bid to introduce a more efficient substitute. SIS will be staffed by 1,500 personnel, some 300 fewer than SDOE currently employs. SIS will concentrate on large-scale financial crimes committed with the assistance of electronic means, such as the Internet. In a bid to ensure corruption-free officials, the government will install internal checks on SIS employees that will help detect any sort of illegal behavior.
