A Manitowoc man was caught in possession of heroin on Tuesday. Officers were called to The Haven men’s shelter in the 1000 block of Marshall Street when they were informed of a man believed to be under the influence of drugs. The Haven staff directed police to the 39 year old man, who was taken into custody on a probation hold. A secondary search of the man at the jail uncovered a plastic baggie containing 0.4 grams of a substance, later identified as heroin. The man was then charged with possession of heroin.
