After nearly three weeks of lurid reporting on a horrifying gang-rape in New Delhi, women in the Indian capital say they are more anxious than ever, leading to a surge in interest in self-defence classes.
New Delhi has long been known as the "rape capital of India", with more than twice as many cases in 2011 as the commercial hub Mumbai, and special care is taken by most women when travelling at night or on public transport.
But the December 16 gang-rape, in which a 23-year-old student was repeatedly violated on a moving bus and assaulted with an iron bar, has brought concern to new levels amid increased focus on the city's safety record.
Self-defence trainer Anuj Sharma says he has fielded a flurry of calls from concerned women interested in taking classes with his Invictus Survival Sciences training institute in south Delhi.
"There has been a certain surge in the level of demand for services like self-defence and personal protective training," Sharma told AFP at a class in a school hall, echoing comments from other martial arts experts in the city.
"I think this infamous case has forced people to think that they can no longer put this (safety issue) on the backburner, self-defence is a priority for them," he said.
Smriti Iyer, a 23-year-old student like the Delhi victim, says she started coming to Sharma's classes to protect herself better and her example has sparked interest in other friends.
In the classes, Sharma teaches her basic self-defence, including how to squirm free from the grip of an attacker and disable them with a punch or kick to the groin.
"I think women have always known that they have to look after themselves, but after this incident a lot of people of my age have really started taking this up," said Iyer.
Across the sprawling city of 16 million, shopkeepers say sales of pepper spray and rape alarms are up, while many young women report that relatives have become more concerned than ever about their welfare.
One newspaper reported this week that women had started coming forward to apply for gun licences.
Jai Shankar, owner of a general store on the Janpath main road in central New Delhi, told AFP that sales of pepper sprays had been "brisk" since the gang-rape, which has galvanised disgust over rising crime against women.
"Earlier we would sell just a few cans in a month. But more women have been coming to my shop asking for the spray," he told AFP.
Ashima Sagar, a 22-year-old sales assistant in Shankar's shop who takes the "relatively safer" metro train with reserved carriages for women at night, says her mother has become almost paranoid.
"I leave my workplace around nine in the night. After this incident, even if I am late by 10 minutes, my mother gets anxious and calls me to find out if I am OK," Sagar told AFP.
In the outsourcing industry, rocked by a rape and murder of an employee late at night in 2005, some companies have begun providing extra security to women staff who work shifts around the clock.
"After the Delhi incident, we ensure that at least one security guard is present in our late-night cabs," Anurag Mathur, a human resource executive in a Delhi-based company, told AFP.
A survey by industry group ASSOCHAM published on Friday showed a 40 percent fall in productivity of women employees at call centres and IT companies because many had reduced their hours or had quit.
As anxiety takes root, meaning in many cases that women simply stay at home more, activists have raised their voices to condemn the state for failing to offer protection.
"Why should we live in a society where every woman is made responsible for her own security and safety? What we need really is a system which will protect us," said Ranjana Kumari of the New Delhi-based Centre for Social Research.
This has been the source of sometimes violent protests against the government over the last two and a half weeks as incensed women led marches and demonstrations in cities across the country of 1.2 billion people.
The statistics show however that any self-defence techniques are most likely to be needed against a family member or neighbour, with more than 95 percent of alleged perpetrators in rape cases being someone known to the victim.
There were 24,206 cases of rape registered in 2011 in India, according to the National Crime Records Bureau, but this is thought to be gross under-representation of the problem.
In the cities, 17 percent of cases were recorded in Delhi compared with 8.6 percent for Mumbai.
