Feb. 15 (UPI) -- Chicago police arrested two suspects Friday after they were questioned in relation to the attack last month against actor Jussie Smollett.
Authorities have not released any charges for Obabinjo Osundairo and Abimbola Osundairo, brothers in their mid-20s.
"Detectives have probable cause that they may have been involved in an alleged crime, and we are working to corroborate the allegations and investigative timeline as our investigation continues," Chicago Police Department spokesman Anthony Guglielmi said.
Smollett, 35, filed a report Jan. 29 with Chicago police stating he was assaulted by two men who also threw an unknown chemical substance at him. He told police the men shouted racial and homophobic slurs at him.
The next day, Chicago police released two stills from surveillance footage of two individuals walking down a street with their backs to the camera.
Investigators believe the Osundairo brothers are the two men pictured in the surveillance images.

A source told the Chicago Sun-Times that at least one of the two suspects worked on the show Empire with Smollett and that both are from Nigeria. The two traveled to Nigeria on Jan. 29 and returned Wednesday, when they were detained.
Smollett's representative said he was "pleased" Thursday when he learned of the questioning, NBC News reported.
