Residents of a Chicago condo whose building will be in the eye of the NATO storm are being warned that they should move out for the weekend or risk being trapped inside by rioters.

The people living in the 17-floor Library Tower building at 520 South State Street were warned in a letter from condo management that "we are STRONGLY recommending that all residents find places to stay during the conference from May 18 through May 21."

NATO summits often attract crowds of thousands of protesters. Currently, a march is planned on Sunday, May 20, from the Petrillo Band Shell in Grant Park past Library Tower on State Street to McCormick Place.

The condo is hiring two off-duty police officers to provide security; those cops will be armed.

"In the event of a riot or the potential of one near the building, all access doors will be locked including the garage door," the letter continues. "For everyone's safety, we will be instructing anyone in the building to stay in his or her unit."

"I can't just leave my garage whenever I want. They'll be holding us hostage in here," said resident Sebrina Krielinger.

"It's just pretty shocking to see and hear things are going to be scary in your own home," said resident Jeff Lunz. "I think they've got everyone's best interest in mind."

The letter also warns:

"We are strongly recommending that you do not have any guests over during this time including dog walkers and cleaning companies."

"There will be absolutely no deliveries or moves permitted between Friday, May 18 and Monday, May 21."

"The revolving door will be locked on Friday morning."

"I'm inconvenienced by parades and a lot of other things. I can't get out on the day of the Thanksgiving Day parade. So that's just a part of city life," said Lunz.
