Malabar Hills - Vacant place in the D ward in Malabar Hills premises should be filled by planting trees. Yuva Sena Leader Hemant Dudhvadkar wrote a letter to BMC on Thursday in this regard. Hemant also challenged BMC saying," If trees are not planted, BMC will have to face the music." Many trees have been cut down in past two years in D ward. No action has been undertaken by the municipal corporation in regard to this even when residents too wrote a letter.
