The Delhi gang-rape effect seems to have left with bad memories for most of the young woman of Hyderabad. Ever since the horrific rape of Nirbhaya, city girls are queuing up before various types of self-defence centres to learn martial arts.Cashing in on the need for self-defence techniques, academies in the city have introduced short-term and long-term programmes for women. The programmes range between 15 days and six months for the age group of 16 to 28 years. The coaching centres have also employed women trainers for the comfort of students. The fee range is anywhere from Rs 1,500 to Rs 6,000 depending on the course.
