Civic employees cleaning drains outside the thane railway station found rs 3,000 in demonetised currency notes in a gutter on saturday. The staffers informed the thane police and handed over the notes. Several beggars line up just ahead of the drain where the money was found. We suspect that someone gave them the old currency notes. When they realised the money was of no value, they must have thrown the notes in the gutter, an officer said.
