Delhi's new Transport Minister Saurabh Bharadwaj lost his mobile telephone at the Ramlila Maidan where he was sworn in Saturday.
"Lost my micromax mobile at Ramlila Maidan," Bharadwaj tweeted.
His younger brother Gaurav Bharadwaj told IANS: "He lost his phone yesterday and is now without one. He has not filed a police complaint as it is not a case of theft."
Tens of thousands of people thronged the sprawling Ramlila Maidan in the heart of the capital Saturday to see Arvind Kejriwal take oath as Delhi chief minister along with six ministers, Bharadwaj included.
