New Delhi, Dec 16 (ANI): Students on Tuesday (December 16) penned the longest letter to Prime Minister Narendra Modi seeking safety for women and faster penalty of the accused as the country observes the second anniversary of the brutal gang rape of a 23-year-old physiotherapy student on a bus in New Delhi. A poll published by a newspaper said 90 percent of 2,557 women surveyed, did not see any improvements in safety. The same survey found 86 percent of respondents avoided going out alone after dark. Police and government officials argue that a host of measures have been introduced to improve safety, but add that violence against women is a far more deep-rooted problem which cannot be solved easily.
