After the recent gangrape of a 23-year-old in south Delhi, women of Delhi have been signing up to self-defence classes.

Delhi, called the "rape capital of India", has seen an increase in defence class enrolment since the brutal rape. A girl is raped in Delhi every 14 hours and the recent case has seen an increase in media attention in sexual harrassment cases as well as a rush for gun licences by women to protect themselves.

Self-defence trainer Anuj Sharma told the AFP news agency that he has had 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 said.

"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.

One woman who is planning on attending another class organised by a separate company, which is to be held this weekend and is free for women in January, says "Truth is, we need to take our safety in our own hands if we don't want to spend our lives in fear."
