Billionaire industrialist Pankaj Oswal's daughter Vasundhara, who has been detained in a Ugandan prison, is being forced to live in filth, her sister claimed. "She's...already fallen sick two times in three weeks...as she is forced to take a bath with...cold water," Riddhi said. Vasundhara, who is lodged with convicted murderers, also does not have access to vegetarian food, she added.
