DEVELOPING: The man suspected of a bombing attempt on a Colorado mall has been captured by police, Fox News confirms.
Earl Albert Moore, 65, was arrested and taken into custody Tuesday morning in Boulder, Colo., the FBI said in a press release.
Authorities launched a nationwide manhunt for Moore over his alleged involvement in an attempted bombing last week at the Southwest Plaza Mall in Littleton, Co. The FBI has referred to the incident as an act of domestic terrorism.
The explosives did not detonate, but the incident alarmed authorities and residents because the plan took place on the 12th anniversary of the shootings at Columbine High School in Littleton.
Investigators, however, said Monday that the event was not likely related to the anniversary. Authorities have found a motive but aren't releasing additional information, an FBI spokesman said.
Moore, who is considered dangerous, was released from federal prison April 13 after serving time for his conviction in the May 2005 robbery of a West Virginia bank, according to the U.S. Bureau of Prisons. Federal court records show that Moore pleaded guilty to robbing the bank in Crab Orchard, W.Va., of $2,546.
A judge sentenced Moore to between 15 and 19 years in prison, but a federal appeals court in 2006 ruled his stiff sentence was "unreasonable" and Moore's sentence was reduced to seven years.
Moore was photographed walking into the Southwest Plaza Mall around noon Wednesday carrying a plastic Target shopping bag, FOX 31 reports.
Marshall Wood, the employee who found the explosives ablaze in the hallway, described them as camping propane canisters, which are readily available at many stores.
“When I first looked, all I really saw were flames,” Wood told Fox 31. “It looked like there was some melting going on.”
The explosives included two propane canisters and a pipe bomb that were placed in a hallway near the mall’s food court.
The mall, which was evacuated, is a busy indoor shopping center in Jefferson County.
