Chicago police department begins investigation into the assault of Empire star, Jussie Smollett

Chicago State police department confirm that they are expanding the search area for surveillance video of actor Jussie Smollett's alleged attackers.
 Already, Chicago police say they have "reviewed hundreds of hours of video" as they search for footage of the reported attack on actor Jussie Smollett. They've now expanded their search to the Chicago riverfront, Chicago police spokesman Anthony Guglielmi said.
Here's Guglielmi's full statement:
“Chicago police detectives continue to investigate serious allegations of a potential racially charged hate crime that took place in the downtown area Tuesday morning around 2 a.m. The Streeterville neighborhood where the alleged attack occurred has a very high density of city and private surveillance cameras. As of 10 p.m.
Tuesday, detectives canvassed and reviewed hundreds of hours of video and have now expanded the search area along the Chicago riverfront hoping to find video to be able to release a public description of the offenders. Unfortunately, thus far we have not found any helpful information on a suspect or a suspect's vehicle to be able to share. 
We are taking this investigation very seriously and detective teams will broaden our search area and work around the clock to look for video on traffic cameras, CTA buses and neighboring thoroughfares which could have captured the offender's movements. The victim in this case is cooperating fully with detectives and our investigation continues.”
