Police detectives in Chicago investigating the attack on “Empire” actor Jussie Smollett said they found footage of “people of interest” from a surveillance camera, NBC Chicago reports. A police spokesman said the subjects seen on the video are wanted for questioning in connection with the attack early Tuesday morning.

“Police said they were planning to put out a community alert with photos from the camera at some point Wednesday evening,” the story reports.

The report adds: “Detectives have reviewed surveillance footage of Smollett walking to a downtown Chicago apartment after an early-morning visit to a Subway restaurant, but none of it showed an attack on the actor, a police official said Wednesday.

“Investigators ‘for the most part’ can confirm the route Smollett took early Tuesday when he says he was attacked by two masked men along a street in the Streeterville neighborhood, police spokesman Anthony Guglielmi said. However, there are gaps and none of the footage police have reviewed shows an attack, he said.”

Earlier media reports indicated the FBI was handling the investigation, but it appears the agency is mainly focused on a threatening letter received by Smollett last week. The letter was reportedly sent to the Fox studio in Chicago where “Empire” films.

“Guglielmi said detectives who are investigating the allegations as a possible hate crime have looked at hundreds of hours of surveillance video from businesses and hotels in the heavily monitored area,” NBC Chicago reports. “But he said they still need to collect and view more.”

Smollett has been released from the hospital, according to media reports, and is said to be recovering from the injuries he received in the attack.
