The Federal Bureau of Investigation (FBI) announced on Monday that it had arrested a Minnesota man for plotting a "localized terror attack."

A press release from the Minneapolis Division said that "special agents of the Federal Bureau of Investigation, in conjunction with the Montevideo Police Department; the Chippewa County Sheriff’s Office; the Bureau of Alcohol, Tobacco, Firearms, and Explosives; the Minnesota State Highway Patrol; the Bloomington Police Department; the Minnehaha County Sheriff’s Office (South Dakota); the Minnesota Department of Natural Resources; and members of CEE-VI (Cooperative Enforcement Effort), executed a search warrant at 1204 Benson Avenue, Lot #8, in Montevideo, Minnesota. Several guns and explosive devices were discovered during the search of the residence" on Friday.

Buford "Bucky" Rogers, 24, was arrested for unlawful possession of a firearm by a felon. An Associated Press report said that he had previously been convicted for felony burglary in 2011 and a misdemeanor charge of dangerous handling of a weapon in 2009.

"The FBI believes that a terror attack was disrupted by law enforcement personnel and that the lives of several local residents were potentially saved," the FBI said in a statement.

A federal affidavit obtained by the AP indicated that Molotov cocktails, pipe bombs and a Romanian AKM assault rifle had been recovered from Buford's residence at the mobile home park in Montevideo.

Rogers reportedly told authorities that he had fired the assault rifle on at least two occasions at a Granite Falls gun range.

The FBI declined to say if Rogers was acting alone or if other arrests were expected.

FBI sources described Rogers as a "militia type" to ABC's Pierre Thomas.

"'Bucky' Rogers, MN man allegedly working on terror plot, formed group w/ anti-govt tendencies called 'Black Snake Militia' per Montevideo PD," ABC News producer Matthew Jaffe reported.
