If this is true and all that happened was these people closed their bank accounts...

October 15, 2011 6:12 PM By Citibank Public Affairs
Citibank Public Affairs issued the following statement regarding today's incident: "A large amount of protesters entered our branch at 555 La Guardia Place around 2:00 PM today. They were very disruptive and refused to leave after being repeatedly asked, causing our staff to call 911. The Police asked the branch staff to close the branch until the protesters could be removed. Only one person asked to close an account and was accommodated."
To be clear: no one was arrested for closing an account; we didn't lock people in our branch - the police decided to close the branch; and we didn't ask for anyone to be arrested - that is a police decision.
Gonna be interesting to see how this one develops. I'm sure there were some in there just being disruptive but I can imagine a few could have been legit at least.
