An old video of Infosys co-founder Narayana Murthy criticising actor Kareena Kapoor for ignoring her fans during a flight is going viral.

In a conversation at IIT-Kanpur, Mr Murthy voiced his surprise at Kapoor's lack of acknowledgment towards her fans.

Though his wife, Sudha Murty, tried to defend Ms Kapoor, Mr Murthy continued with his remarks and gave details of the incident involving the actor.

The other day I was coming from London, and next to me was Kareena Kapoor, sitting in her seat. So many people came to her and said hello. She didn't even bother to react," said Narayana Murthy.

"I was a little bit surprised. Whoever came to me, I stood up, and we discussed for a minute or half a minute-that's all they were expecting," Mr Narayana Murthy added.
