Just got this from a guy who works downtown.
FYI - The NYPD has notified building management about a large demonstration that will take place tomorrow, Saturday, September 19th in the downtown Wall Street area. Several groups will be gathering in various locations throughout the financial district. These groups may attempt to disrupt wireless networks in the area and may attempt to gain access into building lobbies to hold protests. The NYPD is saying this demonstration could attract anywhere from 5,000 to 20,000 protestors.
The building will be operational tomorrow however, as a precaution, they are keeping the entrance doors locked. Each person must show their Building I.D. access card at the [redacted] entrance to gain entry.
The [redacted] Garage (parking garage at [redacted]) will be closed tomorrow.
The building will have extra security working with the NYPD.
