LAKE QUIVIRA, Kan. -- Authorities are warning residents about a group of young people going door-to-door asking for money.

KMBC's Jim Flink reported Tuesday that the group uses high-pressure sales tactics and lies hoping to con residents out of a lot of money.

Flink said that three people were arrested after saying that they were raising money for everything from volleyball teams, to children's charities, to hospitals.

In reality, Flink reported that they are part of a group called Ultimate Power Sales or United Family Circulation, which is a for-profit company out of Georgia.

Investigators said that the group recruits young adults from all over the country who then use high-pressure sales tactics with stories that they can't back up.

Flink said that the young people travel in packs of 20, targeting upper-class neighborhoods, like Lake Quivira.

"They were telling people they lived in the neighborhood, that they were children of neighbors, and that they were selling for hospitals, soccer teams, and it just didn't pan out," Lake Quivira Police Chief Patrick McCarthy said.

Johnson County Assistant District Attorney David Harder said that the stories get even better.

"They've used the pitch that they're trying to get over a fear of public speaking," Harder said.

Flink said that all of it is a violation of the Kansas Consumer Protection Act.

"They're very practiced. They can make a lot of money, and they'll hit 30 to 100 houses a day," Harder said.

Flink said that the people involved are in competition to make money. Some of them make more than $50,000 a year.

Harder recommends that residents ask anyone soliciting to produce a license and documentation. Legitimate organizations have phone numbers and literature. If the story doesn't add up, authorities say to call the police.
