NEW YORK (AP) - A letter with suspicious powder was sent to New York City's mayor on the same day that suspicious powder was sent to at least five hotels near the site of the Super Bowl.
NYPD Commissioner Bill Bratton told the Daily News on Saturday the letter sent to Mayor Bill de Blasio Friday was harmless.
It wasn't immediately clear where the letter was sent or who received it. The mayor's office didn't respond to a request for comment.
Bratton says it arrived the same day suspicious powder was mailed to at least five New Jersey hotels near the site of the Super Bowl and to the Manhattan office of former Mayor Rudolph Giuliani.
Authorities are still testing those substances but have said they don't appear to be dangerous.
