UPDATE: And now those two Nigerian persons of interest are now suspects (viaAssociated Press):
Chicago Police say the two men being questioned in the attack on “Empire” actor Jussie Smollett are considered suspects.
Department spokesman Anthony Guglielimi said Friday that the men are in custody and have been arrested based on probable cause that they may have been involved in a crime. But he says they have not been charged in the Jan. 29 attack.
Police have identified the men only as two Nigerian brothers.
ABC News added that the two men "have a relationship with Jussie."
