Throwing his weight behind activists protesting against the chopping of trees in Mumbai's Aarey Colony, Shiv Sena chief Uddhav Thackeray on Saturday promised to take action against those responsible if voted to power in the upcoming Maharashtra elections. "The upcoming government will be our government, and once we come to power once again, we will deal with the murderers of Aarey forest in the best possible manner," Mr Thackeray tweeted on Saturday, terming it as an "important issue" that he won't hesitate to address.
