The National Competition Protection Agency will initiate a thorough and urgent investigation of how legal and justifiable the recent rise in fuel prices is, announced the Agency's head, Viorica Carare, after check-ups carried out on Monday at the filling stations in Chisinau and its suburbs, Info-Prim Neo reports. “Fuel prices have increased in price over the weekend. This morning we decided to conduct a surprise inspection. At the scene we found that so far prices at the pump have risen at the stations owned by Tirex Petrol. Based on preliminary information, the justification of the raise is not very clear. We will urgently initiate a thorough investigation”, Viorica Carare told reporters. Over the course of this week the Agency will constantly monitor prices at the pump.
