The Polit Bureau of the Communist Party of India (Marxist) has issued the following statement on September 4. THE reports of the CBI Director Ranjit Sinha meeting a number of persons who were being investigated by the agency at his residence, raises disturbing questions. Some persons were charge-sheeted by the agency and some have dubious antecedents. It is highly improper and irregular for the head of the premier investigating agency to be meeting such persons and that too at his residence. There has to be a high level probe into the matter and suitable action taken thereafter.
