Duane Davis Sr. was charged late Monday with placing a phony destructive device outside the old Baltimore County courthouse. Police said a cell phone, an electronic device and a note signed by the 51-year-old Davis were attached to the toilet, and it was decorated with newspaper clippings and photos.
A police spokesman said the county bomb squad investigated and the toilet proved harmless.
Davis is being held, with bail set at $200,000. He is also charged with making a false statement on Facebook about leaving destructive devices outside the building.
It was not immediately clear whether Davis had an attorney.
