This was stated by an official quoting Varthaman after he received the pilot at the Attari-Wagah border soon after his release by Pakistan.
Varthaman was captured by Pakistani authorities on February 27 after an air combat between the air forces of the two countries, a day after New Delhi had conducted counter-terror operations in Pakistan's Balakot.
"We are happy to have him back," said a top IAF officer shortly after Varthaman was handed over to Indian authorities.
Reading out a brief statement, Air Vice Marshal R G K Kapoor, assistant chief of Air Staff, told a posse of reporters that the pilot will be taken for a detailed medical examination as he was subjected to lot of stress during his nearly three-day captivity.
"He will be taken for a detailed medical checkup. The officer has had to eject from a plane which would have put his body under immense strain," said Kapoor.
The Air Vice Marshal did not take any question from the media.
