Police on Friday said that three persons, including a woman, were arrested in Maharashtra’s Palghar district for allegedly operating an interstate gang involved in blackmailing and extortion.

Valiv police station senior inspector Jairaj Ranavre said a woman who was living as the tenant of a builder in Vasai some two years ago accused him of impregnating her and threatened to file a rape case if he did not pay Rs 1 crore.
