The neighbourhood watch programme was started last year in July.The only area in the city to have a neighbourhood watch programme is Zone 9 in the western suburbs, which includes Versova, Juhu, DN Nagar, Santacruz, Bandra, Khar, Oshiwara and Amboli.
As far as I know this concept was introduced in Victoria. Neighbourhood watch is a community crime prevention scheme. The concept also started in Mumbai.
