An Irving man is no longer being investigated by the FBI after suspicious material was found by the Irving Fire Department in his apartment.
Firefighters discovered the material when a small fire erupted in a second-story apartment of 41-year-old Sharif Ahmed Nour in the 3600 block of Block Drive.
Fire crews called Irving police, who arrested Nour on suspicion of possession of prohibited weapons, a third-degree felony.
Tests by Irving police's bomb squad determined that the material did not pose an imminent danger, but investigators called the FBI and the Joint Terrorist Task Force.
On Monday, the FBI said the man posed no terrorism threat and that evidence didn't warrant any federal charges being filed.
Officials have not said what the material was.
A taxicab parked in the apartment complex's parking lot is a part of the investigation, but police would not confirm if the man drives the taxi.
