BELGRADE - Disgruntled fans of a Serbian regional league club have vented their frustration at Macva Sabac's repeated failure to gain promotion to the national second division by digging a grave on their pitch, a club official said Tuesday. The two-metre long shallow grave was also adorned with a cross carrying a gruesome message which read: "Second division or this". The gave had been dug on Macva's pitch in the western town of Sabac on Monday. "We cannot believe that someone could have such an idea," Zvone Jovanovic, a Macva official told AFP. Jovanovic said the police have opened an enquiry into the incident, although the people responsible remain unknown. Despite the somewhat obvious nature of the message's origin, Jovanovic said he was "convinced that it was not done by our fans." –AFP
