(Boring, OR)  --  A man wanted on several outstanding warrants is in custody after being arrested following a two-hour standoff in Boring.  Clackamas County authorities say Raymond Wilebski ran into his residence after deputies spotted him Saturday night on Southeast Kathy Lane in Boring.  A SWAT team surrounded the home after a report that Wilebski may be armed.  After about two hours, tear gas forced Wilbeski out of the house and he surrendered.
