Between 66,000-8,000 minks are loose in one part of Northumberland County. PA State Police say someone cut holes in the fence of a fur farm near Sunbury overnight Sunday. The animals, housed at Richard H Stahl Sons Incorporated on State Route 890 in Rockefeller Township are considered aggressive and anyone coming in contact with a mink is advised to stay away. The animals can also be dangerous to pets. The PA Game Commission advises, do not try and catch or trap them.
