The CBI has sent a request to the United Kingdom seeking details of financial dealing of London- based Ashish Patel, the owner of AM Films and AM Vans, who is named as an accused in Commonwealth Games corruption cases. The agency has sent a Letters Rogatory to Britain.Official sources said, the sleuths probing the allegations of corruption in Commonwealth Games have tracked an e-mail written by Patel to Organising Committee treasurer M Jaychandran which, they claim, confirms that kickbacks were paid to CWG Organising Committee Chief Suresh Kalmadi. Patel's mail mentions details of money which was allegedly paid to Kalmadi and says that the dues should be cleared as swiftly as possible to his companies whose services were used during Queen's Baton Relay.The non-cooperation from Patel in the probe had prompted the agency to adopt a more rigorous legal path of sending Letter Rogatory to the United Kingdom in this regard. The CBI had charged former OC Joint Director General T S Darbari, former Deputy Director General Sanjay Mahendroo, Director Raj Singh, Patel, and other unknown persons under relevant provisions of Indian Penal Code.
