Police have registered an FIR against a prominent builder in south Mumbai for alleged violation of certain conditions while flying a drone in the city a day before Prime Minister Narendra Modi's visit earlier this week, an official said on Friday.

The incident took place in Pedder Road area on Monday, he said. "As PM Modi was scheduled to go to Bandra Kurla Complex (BKC) in the city via Pedder Road the next day (Tuesday), the police had inspected the entire road for security reasons. However, a local resident on Monday informed the police that he had seen a drone flying in the area," the police official said.
