Someone has attacked a Warsaw bus again. Two windows in bus number 158 were damaged. The police still do not know who has been shooting and if this was a shooting at all. Tuesday 2pm. Bus No. 158 turns left and heads for the last stop in Ostrobramska district. There are a few passengers inside. Suddenly, they hear the crack of broken glass. The bus stops. The driver gets off to take a look at the windows, then he informs the police. This has been the ninth such incident in recent weeks. Someone has been persistently attacking the buses and trams of Warsaw public transport. The attacks result in cracked or broken windows. “So far we haven’t found any bullets,” says sub-inspector Maciej Karczyński, spokesman for the Warsaw Police Department. It is possible that the ‘sniper’ uses an air gun, for which a license is not needed. There was a similar incident in Warsaw in November: a drunken man shot at a tram driver for fun. He was arrested 15 minutes later. The police do not know if there is only one person responsible or a group. The media have already publicised these accidents so there might be copycat attacks. “We need information from citizens in order to identify the ‘sniper’”, appeals Maciej Karczyński. A special unit has been created by the police in order to investigate this mysterious series of acts of vandalism. Does it mean that the problem is serious and should we be afraid to use public transport? Officer Karczyński reassures the public that “This is only damage to public property. Nobody was injured”.
