"He (Rauf) has associated himself with bookies in a manner that brings him under suspicion and so we are proceeding against him... Including issuing Letters Rogatory," Roy, Joint Commissioner of Police (Crime), told reporters.
A Letters Rogatory is a formal request from a court to a foreign court for judicial assistance.
Rauf was said to have left India on May 21, the day actor Vindoo Randhawa was arrested for his alleged role in the betting scam.
Vindoo, according to crime branch, had facilitated the escape of Sanjay and Pawan to Dubai as bookies across the country faced the heat following the arrest of three Rajasthan Royals players including India pacer S Sreesanth for spot-fixing IPL matches.
A SIM card given to Rauf by Sanjay was destroyed at the instance of Vindoo before the actor's arrest in the IPL betting case. Rauf used the SIM card during his stay in India over the last three years.
