Denver Post | An improvised explosive device was detonated against the exterior wall of a building housing the Colorado Springs chapter of the NAACP on Tuesday, officials said.
The explosion knocked items off the office walls but no one was injured.
Agents from the FBI Joint Terrorism Task Force and the Bureau of Alcohol, Tobacco, Firearms and Explosives went to the scene after the blast to gather evidence and place markers.
The FBI said that a gasoline can was placed next to the device but the contents did not ignite.
According to the the FBI, officials are seeking a "potential person of interest," described as a balding white male, about 40 years old.
"He may be driving a 2000 or older model dirty, white pick-up truck with paneling, a dark colored bed liner, open tailgate, and a missing or covered license plate," the FBI said in a statement said.
