The Pottawatomie County sheriff is warning residents to be aware of scammers also referred to as "gypsies."
Authorities said in the latest incidents, they show up offering to complete an asphalt job on a driveway and quote the victims a price.
After finishing the job, they request up to triple the original quote.
Deputies said they also try to scare people into paying them.
"They call the guy 'the enforcer,' a bigger guy that's coming around. I guess he's trying to use intimidation factor to get these people to pay," Jimmy Brewer of the Pottawatomie County sheriff's office said.
News 9 was told the scammers have Louisiana tags.
Anyone with information or questions can call the sheriff's office at (405) 273-1727.
