Scratch that, it's most likely a probe as it says it is. Maybe this is something more like a mid-air collision. The Feds were messing around on Merope. They collide with someone else messing around on Merope. Both send out a distress. The Probe picked up the distress some time later, but the Feds (being closer) pick it up. And then they pick up a lot of these UPs. This way the person sending the probes just doesn't know what happened. In the mean time the Feds get new shinies. This forces the owner of the UP to come in person... we're somewhere around that point now... maybe?
