The 'unanimous' decision to suspend IHF was taken at an emergency meeting called by the IOA following the sting operation which caught Secretary K Jothikumaran purportedly accepting bribe to select a player in the national team.
The ad-hoc commiittee will have hockey greats such as Ashok Kumar, Dhanraj Pillay, Ajit Pal Singh and Zafar Iqbal as the other members.
"It is a painful decision that we made today. But it had to be taken since there were corruption allegations. We have taken the decision after discussions with former Olympians, captains and all those who have played for India," IOA President Suresh Kalmadi told a packed press conference.
"Gill was there (meeting) throughout. It was a unanimous decision and no one spoke against it. We have great respect for K P S Gill and it is not personal. Jothikumaran did not come unfortunately, we wanted to hear him. It was an opportunity for him to present his case," he said.
