Susmita Chakarvarti (45), the wife of Manas Chakarvarti who is a ground staff in Kingfisher Airlines, was found hanging from the ceiling in her DDA flat in south-west Delhi's Manglapuri at around 1:30 PM.
She was rushed to a nearby hospital where she was declared brought dead.
A suicide note purportedly written by her was recovered from the spot in which she spoke of being under financial stress due to non-payment of salary to her husband.
"In the note, she said that her husband has not got salary for the past four-five months and that she was unable to cope up with the situation," A K Ojha, Additional Commissioner of Police (South-West), told PTI.
The body has been sent for postmortem.
