"Empire" actor Jussie Smollett has released his first public comments about the incident:
"Let me start by saying that I'm O.K.," Smollett said in a statement released on Friday. "My body is strong but my soul is stronger. More importantly, I want to say thank you. The outpouring of love and support from my village has meant more than I will ever be able to truly put into words."
"I am working with authorities and have been 100 percent factual and consistent on every level. Despite my frustrations and deep concern with certain inaccuracies and misrepresentations that have been spread, I still believe that justice will be served."
The FBI and Chicago PD are investigating have new leads.
Chicago police said an envelope with white powder and a threatening letter with magazine cut outs pasted on paper was received at Cinespace Studios, where "Empire" is filmed, on Jan. 22.
HAZMAT responded, but the white substance turned out to be aspirin.
Police have released photos of two individuals wanted for questioning.
Video of Smollett walking into a hotel after the attack with a noose around his neck, along with the noose and his sweater have also been acquired to help try to identify more clues to find the attackers.
Smollett said he was on the phone with his manager when the attack happened.
His family's statement said this was a "violent and unprovoked attack," and "a racial and homophobic hate crime."
A witness, who requested anonymity, described a "creepy" white man outside the building with a clothesline hanging from his pants, staring at another man near another entrance about 300 hundred feet away.
She told TMZ, "He looked out of place." He had scruff on his face, wearing a blue winter beanie, a blue zip-up sweatshirt with a hood and blue jeans that were too short. He had "thick, grey hunting socks" with camel-colored dress shoes.
She talked to detectives when she found out there was an attack.
