An 80-year-old man, who was kept in a windowless basement for 20 years without basic amenities, has finally been freed, sparking a human trafficking investigation. The man, who has not been named, was found living in 'inhumane conditions' in Helsinki, Finland. Police discovered that the man's room lacked windows, a toilet, and cooking facilities, raising concerns about his hygiene and health. The man was referred to healthcare professionals for immediate care. Local authorities believe he may have been living there for two decades. The shocking discovery led to the arrest of three people, all in their 60s, who were later released. The investigation revealed that the victim voluntarily moved into the house over 20 years ago, and his health deteriorated over time. The man's discovery prompted a human trafficking investigation due to fears that the perpetrators took advantage of his vulnerable position. Police also raised concerns that the man may have been subject to degrading conditions for potential financial gain. The suspects, who may have known the victim for some time, are not related to him. The investigation is ongoing as police determine the length of time the man lived in the basement and whether any crime was committed.
