Updated: A large contingent of police officers responded to the Bank of America on Market St. and 20th Ave. at 6:30 this evening.

“They all seemed especially interested in the back entrance – not the front entrance on Market,” writes Robby Delaware, who sent us this photo (and more right here.) “Seemed odd, especially since the bank was closed.”

“It appears it was a false alarm,” Detective Mark Jamieson with the Seattle Police Department tells us, “Quite possibly a courier dropping off a bag, tripping the alarm.” (Thanks Robby!)
