© Gethin Chamberlain for the ObserverYoung women from the Red Brigade walk through the Midiyav slum in the city of Lucknow. Their leader, Usha Vishwakarma, 25, is in white.
The male tormentor of the young women of the Madiyav slum did not spot the danger until it was too late. One moment he was taunting them with sexual suggestions and provocations; the next they had hold of his arms and legs and had hoisted him into the air.
Then the beating began. Some of the young women lightly used their fists, others took off their shoes and hit him with those. When it was over, they let him limp away to nurse his wounds, certain that he had learned an important lesson: don't push your luck with the Red Brigade.
Named for their bright red outfits, the Red Brigade was formed in November 2011 as a self-defence group for young women suffering sexual abuse in the northern Indian city of Lucknow, 300 miles south-east of Delhi. Galvanised by the gang
rape and murder of a 23-year-old medical student in Delhi last December and the nationwide protests that followed against a rising tide of rapes, they are now gaining in confidence.
From a core membership of 15, ranging in age from 11 to 25, they now have more than 100 members, intelligent and sassy and with a simple message for the men who have made their lives a misery: they will no longer tolerate being groped, gawped at and worse. Their activities are a lesson in empowerment.
