Carrying forward the probe in the Rajiv Gandhi assassination case,the Multi-Disciplinary Monitoring Agency (MDMA),which is investigating the conspiracy angle,is preparing a questionnaire for LTTE financier Kumaran Padmanathan,currently in Sri Lanka's custody. MDMA,which comprises experts from CBI and other agencies and has been granted another extension by the Government despite noting for closure of this unit,has begun the work of preparing questions on the basis of its decade-old findings. These would be sent to Sri Lanka where Padmanathan alias 'KP' is being questioned by security agencies,official sources said. Padmanathan,the alleged financier and a key accused in the Rajiv Gandhi assassination case,was arrested in a Southeast Asian country and brought to Sri Lanka. Declared as one of the most-wanted terrorists by Interpol,he is suspected to be a key person in LTTE's global network for procuring weapons and other equipment. Jane's Defence Intelligence Review,the premier London-based defence magazine,had reported that the LTTE had two international wings - KP Department and Aiyanna Group -that were engaged in global terrorist activities.
