Karnataka Lokayukta Justice Bhaskar Rao's son Y Ashwin Rao has been arrested by a Special Investigation Team from Ranga Reddy district in Telangana in connection with the alleged bribery racket in the Lokayukta office.Ashwin is the first accused in the case and he stands accused of misusing his father’s authority to blackmail officers to pay up, casting a cloud of suspicion over the Lokayukta Justice Y Bhaskar Rao himself. In spite of huge pressure, the Lokayukta has refused to resign from his position.The SIT team was led by DCP (West) Labhu Ram in the operation.Ashwin's arrest comes soon after the SIT arrested Karnataka Lokayukta PRO Syed Riyaz on Sunday.This brings the total number of arrests to six with Shankare Gowda, Sreenivas Gowda and Ashok Kumar being arrested last week.The state government on June 29 set up the Special Investigation Team (SIT), headed by Additional Director General of Police Kamal Pant, on the request of Bhaskar Rao and the Karnataka High Court on July 1 allowed it to probe the charges. With Ashwin Rao's arrest, it will become tough for Karnataka Lokayukta to continue in his position.
