JANESVILLE, Wis. -- Door-to-door magazine salesmen in Janesville have caught the attention of local police, who are trying to determine whether the business is legitimate or a scam.

It was brought to the attention of the Janesville police by a neighborhood watch group over the past few days.

The watch group felt something wasn't right.

Police said the salesmen are young, possibly right out of high school or entering college, and have been telling residents they're from the neighborhood, WISC-TV reported.

The salesmen say they're raising money for a trip to Europe or for school by selling magazines, and even offering to wash cars.

However, after making contact with a few of these salesmen Wednesday afternoon, police found they're from out of state.

Police also feel the story used to rope in customers may be untrue.

Technically, they're not doing anything illegal in Janesville because solicitors don't need licenses to sell magazines in the city.

Still, police are urging residents to be wary.

"It might show up that these people might get their magazines. But what we're seeing is, the articles and papers we've been investigating and looking up on the Internet, people are not getting their products, which makes it a crime at that point," said officer Chad Sullivan of the Janesville Police Department.

City officials are asking that all of these salesmen register themselves and their vehicles through the city.

Police said if someone knocks on your door to sell you a product, ask for identification and ask for more information on the product and company.

Officers will continue to monitor the current group of salesmen while they're in town.
