White House state dinner

A third uninvited guest attended a White House state dinner for India's prime minister in November, the US secret service has said.

It said the man, who was not named, had arrived with an Indian delegation, though there was no indication he had met US President Barack Obama.

A US couple who also gatecrashed the dinner, Tareq and Michaele Salahi, were received by the Obamas.

Three Secret Service agents were placed on leave following the incident.

The White House also said it would put in place new rules to monitor official events.

Both the Salahis and the third uninvited guest are under investigation.

None of the three were given prior security screening to attend the event, though all went through other security checks such as metal detectors, authorities say.

An unnamed US state department official told the Associated Press news agency that the third gatecrasher was a US citizen who was with a group of Indian business leaders that the state department transported from a hotel to the White House.

The state department said it had reviewed the incident and already made changes to the way it handles foreign delegations.

The Secret Service has admitted it was at fault over the Salahis, though its director has said Mr Obama was never at risk.

The Salahis have been ordered to testify before Congress later this month.
