The victim was attacked by one Vijaya Bhaskar following an altercation recently and breathed her last this morning at a government hospital here, relatives and hospital sources said.
The woman, employed with a browsing centre at the suburban Adambakkam, had come under attack last month while she was alone there after Vijayabhaskar splashed acid on her following an altercation.
The accused has already been arrested and lodged in jail, police said.
The victim's brother Vijay said the family was aware of the relationship between his sister and the accused and had approved their wedding proposal.
On February 12, a 23-year-old B Tech graduate working in a private firm died at a hospital following severe burns she suffered in an acid attack at a bus terminus at Karaikal on November 14 by a construction worker, whose overtures she rejected.
