(Portland, OR)  --  Portland police say they've arrested a suspect who attacked officers while armed with a gun and a dagger.  Authorities say 35-year-old Joshua Crocker was one of three suspects inside a pickup truck that police approached early yesterday morning, while responding to reports of a burglary in the area of Southeast 143rd Avenue and Stephens Street.  Officials say Crocker ran from the officers, but they caught up with him and he began swinging his fist at them.  The officers found that Crocker was clenching a handgun between his thighs and wearing a tactical vest that contained a large dagger.  The suspect was arrested on multiple charges after he was disarmed.
