(Portland, OR) -- The FBI is searching for a group of suspects who cut a fence at a Bonneville Power Administration substation in Clackamas County and damaged equipment in an attempt to cause a power outage. It happened early Thanksgiving morning. The BPA is asking for tips in the case. The damage didn't cause a power outage, but officials say it'll cost thousands of dollars to repair. Authorities are asking anyone who sees anything suspicious near a power substation to report it.
