Welcome to mega city Delhi, India's capital and a melting pot of cultures, castes and tradition, all rubbing up against 21st century aspiration. But India's fasting growing metropolis, is also its most dangerous city. With a booming population of 18 million people, a growing gulf between rich and poor and record-breaking crime figures. Delhi is a city of extremes and its police face an unprecedented challenge keeping peace. This is a city where a murder has happened every day this year, crimes against women are up 20%, and India's gang leaders are running criminal rackets from prison.
