A special team of the Enforcement Directorate (ED) will soon visit several countries as part of its probe into the alleged multi-crore hawala and illegal investment case against former Jharkhand chief minister Madhu Koda and his associates.

ED's move comes following issuance of Letters Rogatory (LR) by a Prevention of Money Laundering Act court in Ranchi today, official sources said.

Following the issuance of the LR, a team of ED officials will leave for Liberia, Sweden, Thailand, Indonesia, UAE and Switzerland among other countries, they said.

Koda is currently in judicial custody following his arrest by Jharkhand Vigilance Department under a disproportionate asset case on November 30.

ED had earlier sent out 'source information' to all the mentioned countries based on seized documents including documents suggesting secret swiss bank accounts.

While the LR is a formal legal document issued through the court on behalf of an investigating agency to provide for documents and sharing of relevant details with other countries, 'source information' is data obtained on an informal basis by probe agencies worldwide.
