Suspicious "Substance"?

Far south side:

• Officials today were investigating a report of a suspicious substance package at a Chicago police station on the Far South Side.

  Officials were called to the Calumet District police station, 727 E. 111th St., at about 5:28 p.m. after something suspicious was discovered at the station, said Chicago Police News Affairs....

We're sure it isn't another glaring security flaw in stations that are more like community centers than actual police facilities.

UPDATE: The hazardous material is supposed to be a tuberculosis infected homeless individual living under the stairs in the lobby. Situation normal. Carry on.
