The FBI are looking for "a person of interest" in what they are calling a case of domestic terrorism in Littleton.
A pipe bomb and two propane tanks were found at Southwest Plaza Mall after a fire started just before noon on Wednesday.
Police released surveillance photos of the man FBI agents are looking for.
