The FBI has released a sketch of a person of interest connected with an explosion Tuesday outside of an NAACP office in Colorado Springs. The suspect was previously described by the FBI as a white man in his 40s and balding. The FBI and Bureau of Alcohol, Tobacco, Firearms and Explosives is offering a $10,000 reward for information that leads to the man, who the FBI believes had something to do with the detonation of an improvised explosive device. The device was next to a gas can and against the exterior wall of a building that houses the NAACP Colorado Springs chapter.

The FBI has not yet determined whether the civil rights organization was the target of the explosion, but the president of the local NAACP chapter, Henry Allen Jr., suggested to NBC affiliate KOAA that he thinks it may have been. "Apparently we have the attention of someone that knows we are working for civil rights for all," he said. "That is making some people uncomfortable, so therefore they feel the need to target." No one was injured in the explosion, according to the NAACP.
