Refusing to divulge details about the questioning, Deputy Commissioner of Police (Detective Department), Arnab Ghosh, told PTI that Ghosh has been summoned for a fifth time tomorrow at 12.00 noon for further interrogation.
On whether there was any possibility of Ghosh being arrested, the DCDD said, "What prompted you to come to this conclusion?"
Sources said that the interrogation was held to verify several facts which had come to light since April during the Saradha investigation.
"I cleared all dues of my employees even when the company was facing a major crisis," Ghosh claimed.
