Police have made an arrest in connection to an evacuation at the Hyatt Park Hotel in Midtown Manhattan.

The NYPD held a press conference explaining a female employee of the hotel was cleaning a room when she spotted a white powdery substance in the bathroom and got sick after cleaning the room. Officials have tested the substance and were not able to detect anything of concern in it.

Police investigated the room and found out as a family checked out of the room, a man had snuck in. Police say that man has been apprehended and had been arrested 16 times prior for low-level crimes.

As for how the man snuck into the room, officers say the man may have picked up one of the five keys to the room left behind by the family.

The suspect has been charged and his identity has yet to be revealed.
