New Delhi: A day after Delhi Minister Rakhi Birla’s car was allegedly attacked in Mangolpuri, police on Monday claimed that the vehicle’s windshield was accidentally damaged by a cricket ball but her aides were not convinced. The windscreen of Birla’s car was hit by a cricket ball as a group of boys was playing cricket in the area, a police official said. The incident reportedly happened in R-Block Mangolpuri, which falls in constituency of the Women and Child Development Minister. “Some of us who were also inside the car got down and asked the crowd which had gathered but nobody came forward,” the minister’s aide said. CM Arvind Kejriwal has refused to take any security so as his ministers are following his footsteps.
