Congress has stepped up attack on Modi in the wake of Vanzara's letter slamming the state government.
Vanzara (59), a Deputy Inspector General of Police (DIG) considered close to Modi, had on Tuesday resigned from IPS service accusing the Gujarat government of failing to protect loyal police officers who fought against "Pakistan-inspired terrorism".
The Congress has been demanding resignation of Modi till a CBI probe to ascertain whether the ongoing investigation and judicial process in the Tulsiram Prajapati case had been manipulated, was over.
The Congress unit in Gujarat has called a state wide bandh tomorrow in the wake of Vanzara's letter.
