The development came on a day Congress demanded Modi's resignation in the wake of a sting operation claiming to "expose" a plan by senior BJP leaders to save his key aide Amit Shah in Tulsi Prajapati fake encounter case.
Controversial IPS officer D G Vanzara, who has so far rejected charges of fake encounter killings during Modi's tenure, accused the government of failing to protect officers who fought against "Pakistan inspired terrorism".
In his hard-hitting letter, Vanzara said if policemen could be sent to jail for alleged fake encounters, the place of the state government "should either be in Taloja central prison at Navi Mumbai or in Sabarmati Central Prison at Ahmedabad."
"I would like to categorically state in the most uninquivocal words that the officers and men of Crime Branch, ATS and Border Range, during the period between 2002 to 2007, simply acted and performed their duty in compliance of the concious pro-active policy of zero tolerance towards terrorism of this government after Godhra riots," he said.
"If that is true then the CBI investigating officers have to arrest the policy formulators also as we, being field officers, have simply implemented the concious policy of this government which was inspiring, guiding and monitoring our actions from the very close quarters," Vanzara said.
"By this reasoning I am of the firm opinion that the place of this government instead of being in Gandhinagar, should either be in Taloja central prison at Navi Mumbai or in Sabarmati Central Prison at Ahmedabad," he said.
