Chicago police are investigating cases of suspicious activity at two Loop buildings. One of them is the Sears Tower.
Since 9-11, the Sears Tower in particular has turned up on several lists of possible targets for terrorists. ABC7 news has reported sightings of suspicious looking individuals photographing the building numerous times in the past several years. Law enforcement officials have always publicly downplayed these incidents and they attempted to do that again Thursday.
Sears Tower employees Thursday reportedly received bulletins from building management reassuring them that there is no terror threat. But those bulletins failed to explain the incident ABC7 reported, that three suspicious looking men in a rental car pulled up to the building recently, got out and began studying the building. According to law enforcement sources, they took pictures before building security ran them off, but they never got their identification. Those sources tell ABC7 the car was rented to a fake name.
