Authorities are looking for a man who may have information about an explosion that someone set off near the Colorado Springs chapter of the NAACP.
The blast happened Tuesday outside a barber shop next door to the group's building, which is about an hour south of Denver. Police say there were no injuries and only minor damage.
FBI spokeswoman Amy Sanders says an explosive was detonated against the building, but it's too soon to know whether it was aimed at the nation's oldest civil rights organization.
Sanders says a gasoline canister had been placed next to the improvised explosive device but it did not ignite.
She says investigators are looking for a balding white man in his 40s who may be driving a dirty pickup truck.
