Police have released two Nigerian brothers arrested earlier in the week on suspicion of assaulting Empire actor Jussie Smollett.
The men were picked up by police on Wednesday at Chicago’s O’Hare International Airport and their apartment was searched the following day.
They were questioned on Friday but police were obliged to release them as they had not been charged within 48 hours.
Police spokesman Anthony Guglielmi tweeted: “Due to new evidence as a result of today’s interrogations, the individuals questioned by police in the Empire case have now been released without charges.”
Chicago police said they have new evidence to investigate as a result of questioning the men, but did not elaborate further.
Mr Smollett says he was assaulted on January 29 by two men who shouted racial slurs and put a rope around his neck.
Smollett, 36, said he was out getting food at a Subway sandwich shop in Chicago when the attack happened.
