Guglielmi tweeted: 'Jussie Smollett is now officially classified as a suspect in a criminal investigation by #ChicagoPolice for filing a false police report (Class 4 felony).
As per Variety, they've named the Empire actor and singer - whose claims that he was the victim of a hate crime have in the last week been called into question - as a suspect in another potential crime: filing a false police report.
The charges emerged on the same day that detectives and two brothers who were earlier deemed suspects testified before a grand jury.
Jussie Smolett is one of the stars of TV's Empire.
The men, who were identified to multiple media outlets by their attorney as Abimbola "Abel" and Olabinjo "Ola" Osundairo, were held for almost 48 hours on suspicion of assaulting Smollett before being released Friday (local time).
The Osundairo brothers were set to have their testimony officially documented before a grand jury but Smollett's legal team presented information to prosecutors to delay the brother's testimony, sources told Fox News.
Smollett's attorneys met with prosecutors and police, but it was unknown what they discussed or whether Smollett attended the meeting.
Law enforcement sources now believe that he timed the attack for January 29th with the knowledge the Osundairo brothers would leave to Nigeria.
As for reports that Smollett knew one or both of the Nigerian brothers, his lawyers said, "It is impossible to believe that this person could have played a role in the crime against Jussie or would falsely claim Jussie's complicity". They were later released and are said to be co-operating with the investigation.
Smollett alleged that two men wearing black masks and red hats assaulted him, poured bleach on his head, and placed a noose around his neck while yelling racial and homophobic slurs.
Earlier today, Guglielmi told ABC News that they were seeking a follow-up interview with Smollett and have spoken to the actor's lawyers. Surveillance footage of the brothers purchasing some of these items was obtained by CBS Chicago, which you can see below.
Multiple reports have said they're cooperating with authorities and have accused Smollett of paying them $3,500 to fake the incident. He later pleaded no contest to a reduced charge and took an alcohol education and treatment program.
Fox 32 Chicago reporter Rafer Weigel said he was told an indictment could come in a "matter of hours, not days". "Based on those prior conversations and out of an abundance of caution, last week State's Attorney Foxx chose to remove herself from the decision making in this matter and delegated it to her First Assistant Joseph Magats, a 28-year veteran prosecutor".
