In the heart of Uttar Pradesh's Lucknow, at the busy and upscale Hazratganj market, an anti-Romeo squad - a team of about 30 policemen - swings into action at around 4 pm. Five women constables are also part of the squad led by a Deputy Superintendent of Police. Walking around, they look for potential troublemakers or "Romeos" - the term many use for men who harass women.
