Narrative:

On takeoff of flight from dca, the landing gear failed to retract. We made an uneventful divert to iad with the gear down and landed. I made a normal walkaround prior to the flight and all bypass valves were positioned normally. I did notice a mechanic, with a tool bag, approach the left wheelwell area after I had checked it. The valve was reported to be out of position after the flight.
