The woman was identified as Malati Goltoda (40) of Orangi village, the police said adding that whereabouts of three others could not be ascertained.
The three missing persons included Gopi Goltoda and his wife Srimati Golta. The name of the fourth person was not known, police said.
The four were reported to have been washed away in the flash flood while crossing the river yesterday.
Meanwhile, incessant rainfall caused havoc in the entire district with several roads being washed away by the flash flood in different places. Washing away of Khairput-Mudulipada road has led to no communication with the habitations of Bonda tribals, a particularly vulnerable tribal group (PVTG).
