A group of demonstrators affiliated with the Occupy D.C. movement are suing the Metropolitan Police Department and Bank of America over what they say were unlawful arrests during several days of protests outside a bank branch in downtown D.C.

The sidewalk outside a Bank of America on Vermont Avenue NW is the cool place to camp out these days, with five more members of Occupy D.C. arrested Friday morning after sleeping under the ATM.

Seven members of Occupy D.C. have been arrested this week for blocking the sidewalk after sleeping outside a downtown Bank of America branch. It’s a new tactic, but it’s disputed which Occupy group thought of it first.
