Consulate General of Russia in New York City. Andrei Deev via Wikipedia Police found a 63-year-old security official dead with head trauma inside the Russian consulate in New York City on Tuesday.

"Right now there does not appear to be any criminality. We're just waiting for the M.E. (medical examiner) to determine a cause of death," said officer Sophia Mason of the New York Police Department.

The man apparently collapsed because of a medical issue, New York Daily News reports.

Officers found the man unconscious when they arrived, and paramedics later pronounced him dead at the scene, police said in a statement.

Police responded less than an hour after polls opened in New York following a presidential campaign in which Russia was a leading issue.

The Russian consulate is less than two miles from Trump Tower, the home and campaign headquarters of Republican candidate Donald Trump.

Police were withholding identification of the man pending family notification. Russian consulate officials were unavailable for comment.
