How TWISTED and DEVIANT do you have to be to pull an elaborate stunt just to see one of your coworker's breasts? 

--Last Friday, 44-year-old Russell Kent Gordon of Portland, Oregon was arrested for allegedly planting a SPY PEN on a female coworker's desk . . . so he could tape her using her BREAST PUMP to pump out milk for her new baby.

--Both Gordon and the woman work at a natural resources consulting firm called Mason, Bruce & Girard in Portland.

--The woman noticed the pen last week . . . and realized it was hooked up to a USB drive.  It's not clear how long Gordon had been taping her. 

--But she told her bosses, and they fired Gordon and called the cops.  He was arrested for burglary and invasion of privacy.
