Citadel Investment Group's Chicago headquarters were evacuated yesterday after a suspicious package was found in the building.
The package, later found by police to be "innocuous," was in another firm's offices at the Citadel Center at 131 South Dearborn Avenue. The building was cleared at 3:47 p.m. local time.
It is unclear when employees were allowed to return to the building, but a spokeswoman for Citadel told Reuters that the building was still empty early yesterday evening.
The suspicious device was found in the other tenants' mailroom.
