Etawah, Nov 28 : Passengers at the Etawah railway station were surprised when they heard an unusual announcement from the public address system of the enquiry office. The announcement system sought support for Dimple Yadav, who is contesting from the Mainpuri Lok Sabha seat. According to reports, a group of five to six persons forcibly entered the inquiry office on Sunday and started raising slogans of "Dimple Bhabhi zindabad" from the public announcement system installed there. Railway employees present during the incident told reporters that some miscreants had forcibly entered the inquiry office and after raising the slogans for about 15-20 times, they fled from the spot.
