The woman had yesterday met officials in the Army Headquarters regarding her problem with an army jawan posted at the Sena Bhawan here, they said.
When she came to the South Block again today, they said, she was asked to go back as the jawan had already filed a case against her in a court.
After this, the woman took out a small bottle from her bag and gulped it, they said.
The woman was then first taken to a nearby clinic and from there referred to the Delhi Cantt-based army base hospital, they said.
