Indian captain Virat Kohli says he was upset at how Australia's banned cricketers were treated after the ball-tampering scandal.
Kohli says he felt sad about the treatment of Australians Steve Smith, David Warner and Cameron Bancroft after the trio were suspended for ball-tampering in a Test against South Africa in March.
Cricket Australia banned Smith and Warner from international and state cricket for a year, with Bancroft suspended for nine months.
"What happened after ... I felt very bad,'' Kohli told Fox Sports in an interview to be aired on Saturday.
"The things that happened afterwards should not have happened.
"The things that hit me the hardest was the way they were received at the airports and escorted out.
"It is not my place to comment on the decisions. But to treat people like that for me it was unpleasant to see."
Kohli said he would never want to experience such treatment.
"I have known David and Steve and apart from the battles you have on the field you never want to see something of that magnitude happen to two sportsmen," he said.
"It was sad to see, to be honest. As big a thing as it became, you never want to see anyone go through that."
Kohli said he had been in contact with Warner since the controversy.
"After that event I have always been in touch with David, me and him get along very well, he has been very kind to me," he said.
