The bomb squad determined the devices were actual pipe bombs. They were disabled and rendered inoperable, police said.
Dahm was charged with carrying a dangerous weapon, illegal bomb manufacturing, illegal possession of explosives, first-degree reckless endangerment, and first-degree breach of peace. He was held on $150,000 and was expected to be in court Friday.
