Dhaka: Anti-graft officials in Bangladesh questioned former Prime Minister Khalida Zia yesterday as part of a corruption investigation against her, a lawyer said.

Zia was arrested on September 3 and accused of misuse of power. She has since been held in a makeshift jail inside the parliament complex in the country's capital of Dhaka, pending trial.

Her lawyer said Zia maintained her innocence throughout the 45-minute interrogation.
