FBI probes Colorado Springs explosion near NAACP office

COLORADO SPRINGS, Colo. -- The FBI is investigating a small explosion at a building that houses a NAACP office on Monday, reported CBS Denver.

The explosion happened just before 11 a.m. Monday, reported the station. An FBI spokesperson told reporters Monday afternoon that it was seeking a white male, approximately 40 years of age, as a "potential person of interest."

CBS Denver also reported that the person of interest may have been driving a white older model pick-up truck, with paneling. In addition to the NAACP office, the building reportedly houses an income tax center and a hair salon.

Authorities wouldn't say whether they believed the NAACP was targeted, according to the station.

The Denver chapter said in a statement that it believed the NAACP office was being targeted.

"This is proof that racism is still alive and reared its ugly head in the form of this cowardly act. Regardless of the actions of others, we will continue to fight for the equality of all people," it said in a statement to CBS Denver.

According to investigators, the bomb had three parts -- including gasoline, a so-called rad flare and a pipe.

No one was reported injured and the blast caused minor damage, reported the station.

Anyone with information is being asked to call the FBI Denver tip line at 303-435-7787.
