A man and his son were arrested Thursday on charges they stole metal components from urinals, Birmingham police said. The men hit at least six men's rooms at restaurants in the vicinity of UAB, according to Birmingham police Lt. Sean Edwards. "One of the individuals is a plumber, and he's been using his skills ... to fund his illegal activities," Edwards said. The suspects were not immediately identified. The parts were discovered at local scrapyards. Investigators were puzzled, because the components weren't worth very much.
