Shiv Sena (UBT) MLC Anil Parab on Sunday claimed that a drone was spotted hovering over `Matoshree`, the Mumbai residence of party head and former Maharashtra CM Uddhav Thackeray. The MLC further raised serious concerns about a potential breach in a high-security zone.

However, sources in the police said, "Drone survey with permission by MMRDA was going on in BKC and Kherwadi area."
