Karnataka Lokayukta Justice P Vishwanatha Shetty on Wednesday was discharged from a hospital where he had been admitted after being stabbed repeatedly by a complainant in his office on March 7.

"I am thankful to the doctors and nurses of the hospital who have treated me," Justice Shetty told reporters as he came out of Mallya Hospital in the centre of the city.

Justice Shetty, 73, a former judge in the Karnataka High Court, was stabbed by a 33-year-old complainant, Tejraj Sharma.

He suffered deep wounds to his abdomen, lower chest and hands in the attack. To stem the internal bleeding, he had to be operated on immediately.

Four surgeries later, doctors at the Mallya Hospital declared he was stable and was responding well to the treatment.

A police team led by Joint Commissioner of Police, Crime, N Satheesh Kumar is probing the incident and a report is expected soon, Home Minister Ramalinga Reddy had earlier said.

Sharma, a furniture supplier from Tumakuru, about 70 km northwest from here, had filed a complaint with the anti-graft official about a local government office and was reportedly unhappy that his complaint was not being heard, said the police.

Few days before the incident took place, Shetty had advised the accused not to "squabble" in the Lokayukta office, the Home Minister had said.

Shetty had taken charge as the state's ombudsman in January 2017.
