(KNZA)--The Brown County Sheriffs Office is making the public aware of some suspicious activity being reported in the southern part of the county.

Sheriff John Merchant says his office has received a number of reports about  a white van with several occupants going door to door representing themselves as Kirby vacuum salespeople. He says the female has been described as being in her 30's with blond hair in a pony tail and the male driver with either long hair or beard or both.

Merchant says concerned residents are reporting that at times it appears that the van speeds away from houses when they notice that county residents are observing them more carefully.  While he says the Sheriff’s Office is not wanting to alarm anyone or accuse these people of any wrongdoing, the way they are acting and trying to conduct business not only makes residents suspicious, it has caused concern for several county residents.

Merchant says he has not  been contacted by any Kirby salespeople stating they would be selling in the county.

He is asking residents who notice the van to contact the Sheriff’s Office as he would like to speak with them personally to make sure they are credible.
