The man, who was in charge of security at the installation, was found unconscious yesterday inside the consulate in the Upper East Side neighborhood near Central Park, a New York Police Department spokesman said.
He has not yet been identified, though his age was given as 63. A source close to the police investigation said the man was apparently in ill health.
Police have not yet spoken of a potential crime, and are awaiting the results of the medical examiner's autopsy to determine a cause of death.
