Bomb threat during performance of Jersey Boys

BofA_Theatre Per Chris Jones’ Theater Loop blog, the Bank of America Theatre (The Shubert) was evacuated about half-way through the evening performance after suspicious boxes were found in the alley behind the theatre.  Per the blog:

According to a report from the Tribune’s William Lee, who was quoting a police source, one letter read "this is not a bomb," and the other note said "this is not going to end good." 

Because of time constraints, following the realization that the boxes held nothing dangerous, there was no time left in the evening to complete the second act, and it was canceled. The audience members were informed that ticket exchanges would be available for any Tuesday performance in the month of October.
