Officers investigating a man’s death have appealed to the Polish community for help. Police are treating the death of Michael Jerzy Kuczera, who was from Poland, as “unexplained” and are carrying out further tests. Officers are trying to trace the last movements of the 62-year-old whose body was found in Rugby on Wednesday. Det Insp Paul Thompson said: “We’re especially keen to speak to anyone from the Polish community who knew him.”Police are trying to determine Mr Kuczera’s whereabouts between 13:00 GMT last Sunday and Wednesday morning. A post-mortem examination has taken place and further tests are being carried out to “establish the exact cause of death”, police said. A woman held on suspicion of murdering him was released and will not face further action, police said previously.
