IAF sources said Dhamoon has sought "premature separation" from service even as the process of Court of Inquiry into possible lapses in security at the base was going on.
They also rejected reports suggesting that Dhamoon was sacked after the CoI found holes in security at the frontline base which was attacked by Pakistan-based terrorists on January 2 last year.
Earlier, official IAF sources had said that Dhamoon has already taken premature retirement from service.
"The process of Court of Inquiry is still on," a source said.
