What's going on in downtown Cincinnati today?

Seems that the entire downtown of Cincinnat was shut down around 5pm today due to a “sucpicious suitcase” being found in the elevator of the Hilton hotel.

On my walk home I counted at least 3 ambulences, 2 or 3 firetrucks, at least 6 to 12 police cars and there were uniformed police teams at just about every corner. A whole city block was courdened off as well as about 3 or 4 main city streets were blocked by cop cars with their lights going.
