The Manitowoc County Metro Drug Unit seized items from a Two Rivers home that were being used to created butane hash oil last Thursday. Investigators executed a search warrant on the home located in the 900 block of Rainbow Court, and found several key items in the manufacturing of butane hash oil, including around 100 butane gas cylinders. No one was inside the residence at the time, but two men were identified as living at the residence, and a follow-up is being conducted. The process in which this hash oil is made is dangerous, as an ignition source could cause an explosion.
