Korogosho is one of the many informal settlements in Nairobi. It is a slum. It is there that a group of grandmothers is using elements from wrestling and karate to protect themselves and each other as part of a program that tries to prevent sexual assault.
Ferocious grandmother, 74-year-old Beatrice Nyariara, is in the middle of training.
"It is very unsafe because before we started this group of old women like me, a lot of old women used to be raped by young men. They take drugs, alcohol and when it enters their head, they can't differentiate between their elders and young girls," Ms Nyariara said.Most of the women in this group have either been sexually assaulted personally, or they know someone who has. Kenya police estimate that 85 per cent of sexual crimes are not reported.
Jane Waithegeni was gang-raped more than 10 years ago. She was abducted from a public bus.
