In March, a surprise check in the high-security Arthur Road jail unearthed a cellphone in the possession of Chhota Rajan's men. The cellphone was the source of 972 threatening calls made to prominent businessmen and hoteliers and, investigations revealed, was used by the Malaysia-based don to communicate with his men while they were transported to and from their court hearings. A month later, Jayant Jadhav, a close aide of Bal Thackeray, was gunned down, apparently by members of the Arun Gawli gang. Operations were conducted over cellphones from the Gawli stronghold, Dagdi Chawl, 5 km away. The BPL cellphones, through which the calls were made, were registered in the names of relatives and associates of the killers. Soon after, calls demanding protection money supposedly made by a close aide of Chandraswami and Babloo Srivastava to a Bombay businessman were found to have emanated from Delhi's high-security Tihar jail.
