Zaheera Sheikh, the key witness in the Best Bakery case, has not yet left for Mumbai to depose before a special court in connection with the summons issued for retrial of the case, police said in Ahmedabad on Thursday.

"Zaheera is still in Vadodara. She and her family members are under police protection and at a completely safe location. I am not aware of any summons issued to her," Vadodara Police Commissioner S K Sinha told PTI over phone.

He said she would be taken to Mumbai under police protection whenever it would be required.
