The Ajit Pawar-led Nationalist Congress Party (NCP) leader Zeeshan Siddique on Tuesday alleged that the Mumbai Police have taken a "casual" approach in the investigation into the murder of his father, Baba Siddique, reported the PTI.

Talking to PTI after his meeting with DCP Crime Branch Raj Tilak Roshan, the former MLA asserted that a serious probe in the case should have yielded "solid" progress within a year.
