Earlier in the day, Ghosh said Kumar’s interrogation in the Ponzi scam case was long overdue and claimed many conspirators were still outside the purview of the probe, reports TNT.

“I have lodged a written complaint to the CBI against Kumar this (Tuesday) morning. During our face to face interrogation on February 10, certain Kolkata Police officers were named. But Kumar called up some of those officers after leaving the CBI office that night,” claimed Ghosh, who returned to the city from Shillong, where Kumar is being interrogated.

“These officers were part of the Special Investigation Team (SIT) formed by the state government to probe the ponzi scams. They can be influential leads in the probe. By calling these officers, Kumar is trying to influence the probe,” he alleged.

Unless strict action is taken against Kumar, the outcome of the probe might not be entirely fruitful, he added.

“I have written to the CBI the way Kumar is contacting those who could become important witnesses in the probe, may influence the process. Strictest action should be taken against him,” he claimed.

When asked how did he know about Kumar’s telephonic interactions with the police officers, Ghosh said Kumar himself “accidentally disclosed” that during the interrogation on January 11.

“Kumar himself told the interrogators that he had called some of those officers. He might have disclosed it unconsciously. But his statement is video recorded. There is no need to check his call details for this,” he said.

Ghosh, arrested in November 2013 in connection with the two chit fund scams and later granted interim bail by the Calcutta High Court in 2016, refused to make any comment regarding the investigation or the joint interrogation as the process is still on.

The CBI interrogated Ghosh and Kumar together for several hours on Sunday and Monday, and recorded their statements.
