A 34-year-old forger from Ruse issued false documents for negative PCR tests for travelling abroad. The scheme was revealed when a family from Razgrad crossed the Danube bridge, but without the mandatory tests. They were returned and within just an hour they reappeared at the border with already issued documents. This is what made border guards suspicous. It turned out that the fake tests were signed by a pulmonologist, not a laboratory director, and the doctor's signature was fake.
