An unidentified person along with the official Indian delegation attended the November 24 State Dinner President Barack Obama hosted for Prime Minister Manmohan Singh, a media report said on Monday.
There was no immediate comment from either White House or the Indian Embassy in Washington.
The Secret Service says a third uninvited guest gained admission to the November 24 State Dinner, Politico reported on Monday.
"The person arrived with the Indian delegation, and the Secret Service says 'procedural changes' have already been implemented 'to address foreign delegations under the responsibility of Department of State who are entering facilities secured by the Secret Service'," Politico said.
This adds a new twist to the gatecrashing incident on November in which the Salahi couple had gained entry into the State Dinner without invitation.
The White House has officially closed the case, but has not released the results of its investigations.
