A full-grown leopard was spotted in a residential building in MIDC Andheri East two kilometres from Aarey Colony on Sunday. Forest Department officials visited a non-operational factory near the building where the leopard might have taken refuge and installed trap cages.

Early Sunday morning, a security guard saw the leopard jumping the boundary wall of the building adjacent to a non-functional industrial unit. He informed his colleagues, the Thane Forest Department (Territorial) and the MIDC police station.
