Two men tried, but failed, early Wednesday to steal a four-wheeler in Scott County.
The men were hauling it on a truck on Boyers Chapel Road in Sadieville when it fell off their truck.
Some other people, driving behind it, got out then tried to help the thieves, without knowing the four-wheeler was stolen.
Police say the good Samaritans then noticed the men were acting strangely, so they held down one thief until he pulled out a knife.
The thieves got away.
If caught, the burglars will face robbery charges.
