Dhoni who is a permanent resident of Ranchi having own house there. The letter was received by family members at this very address on Monday. Dhoni family has informed Ranchi police immediately about the letter without late. Knowingly Dhoni reached Ranchi yesterday. Police has increased security around his residence and more policemen is deputed there. Ranchi SSP Sampat Meena is personally monitoring the case. The letter which rocked the administration and media is undersigned by someone Md. Tasleem. And at the end of the letter the sender noted himself as a man of international don Dawood Ibrahim. The letter says about the person to whom the money is to be given. Though this seems to be a false letter as nobody serious enough will give name & address in a letter like this. In the last, the letter underscores the consequences if the said amount of money is not given.
