(09-04) 07:15 PDT Everett, Wash. (AP) -- Two radio station towers toppled after someone used a piece of heavy equipment to knock them down.
General Manager Andy Skotdal says a sign left at the scene Friday says ELF, likely a reference to the Earth Liberation Front. But Skotdal says it's too early to know if the radical environmental group is responsible.
The family-owned station has been fighting opponents of an addition to its existing towers east of Everett.
The station has transferred its radio transmission and remains on the air.
