Ropar: Heavy police force was deployed here on Wednesday as Congress leader Alka Lamba was to appear before the SIT. Meanwhile, Congress leaders staged a protest in front of the SSP’s office here. Punjab Congress president Amarinder Singh Raja Warring and Leader of Opposition Partap Bajwa along with Lamba reached the dharna site. Navjot Sidhu, after expressing his support for Lamba and lashing out at the Aam Aadmi Party, Arvind Kejriwal and Bhagwant Mann in particular, left the spot without taking part in the dharna after he spoke to the media. During the dharna, Congress workers led by Punjab Youth Congress president Brinder Singh Dhillon climbed the main gate of the Mini Secretariat to reach the SSP’s office. Congress leaders, including Warring and Bajwa, along with Alka Lamba, were allowed to enter the office. As other Congress workers tried to enter, the glass of the office’s main door was damaged. After waiting for almost half-an-hour, Warring came out of the office and while addressing the media said that they had come to ask about the reason behind registration of a criminal case against Lamba. SSP Sandeep Garg was not in office, they said, adding that they would not leave without meeting him. Lamba came out of the SSP’s office and said she was told to visit the police station. She was informed that there would be no questioning as her case file was with the Punjab and Haryana High Court.
