Malleswaram Social volunteers have launched a unique initiative – Blow the Whistle – to deter people from converting open spaces into yellow spots. “We have launched this initiative in 2021 to stop people from urinating on the road, especially along the compound wall near 9th Cross and other locations. It has become a nuisance for us. There are occasions where some auto-rickshaw drivers quarrel with me for blowing the whistle,’’ said Vijaya Shenoy of Malleswaram Social.
