In a statement, Karti said it was "deeply regretted" that the privileged forum of Parliament is misused to make "wild and reckless" allegations against a private citizen.
His remarks came as Sinha raised the issue of Aircel- Maxis deal in 2006 and alleged that Karti was benefited by the deal and Chidambaram was the Finance Minister then.
"I categorically state that neither I nor any member of amy family have acquired or hold any share in any telecom company. In particular, I categorically state that neither I nor any member of my family have acquired or hold any share in either Aircel or Maxis," Karti said.
He said the statement was first made by a person who is known to "indulge in making wild and reckless allegations".
"It is unfortunate that the same allegation should be repeated in Parliament by an honourable MP," Karti said.
Sinha alleged that the son of the former Finance Minister got a 5 per cent shares from Maxis.
"Prima facie what happened was a big scam and government should not hush it up," Sinha said, demanding a statement from Mukherjee, who is the Leader of the House, as also the Finance Minister.
