Two men have been arrested in the Christmas day attacks that damaged four electricity substations in Tacoma, Washington that sparked fears of an extremist campaign, the Justice Department announced.
Matthew Greenwood, 32, and Jeremy Crahan, 40, were arrested on December 31 after being identified as suspects based in part on cellphone records, the department announced late Tuesday.
They were arrested with two unregistered short-barreled firearms, one with a homemade silencer, authorities said.
They were charged with conspiracy to damage energy facilities and possession of unregistered firearms.
