The incident occurred at the former minister's residence in Gandhi Nagar.
Sunita Tyagi, 38, wife of Sachendra Tyagi, hung herself from the ceiling fan of her bedroom. She was married to Sachendra Tyagi, the second of three sons of Baleswar Tyagi, 18 years ago.
They had a son, Akash Tyagi, 17, studying in Class 12.
"She was suffering from depression. She was under treatment at Vimhans in Delhi," said Baleswar Tyagi.
