Ticks invade Poland police station, bite 27 officers

Officials say that 27 Polish police officers have been hurt -not in any engagement with criminals, but by ticks that have invaded their police station. The ticks were carried by pigeons that nested on ledges outside the windows of the headquarters in Poznan, a city in western Poland. Firefighters are using special equipment to disinfect filthy window ledges covered in pigeon droppings.
