Madison police say they have no suspects yet in the firebombing of the Wisconsin Family Action location last weekend.
Chief Shon Barnes says there is no indication it might be an inside job.
He says an incendiary device was issued to start the Sunday fire and the inside of one office was damaged.
Graffiti was written on the outside of the building.
Barnes says violence over free speech isn’t the answer despite the increased tension over abortion rights.
