The Army on Tuesday called for a fair and honest investigation in a transparent and time-bound manner to punish the guilty in the Colonel Pushpinder Singh Bath assault incident. Colonel Bath accused 12 Punjab Police personnel of assaulting him and his son over a parking dispute on the intervening night of March 13-14 in Patiala. On Monday, he filed a plea in the Punjab and Haryana High Court seeking transfer of the probe to the CBI or another independent agency.
