A credit card scam has netted two teams of people tens of thousands of dollars, and police say they haven't been caught yet.

Sioux Falls Police Captain Blaine Larsen says investigators believe two Asian women are working with two Asian men, and another team is four black males:

Larsen says the scammers appear to be targeting Walmart, Dollar General, Walgreen's and Target stores in Sioux Falls and other cities driving rental cars and using credit cards stolen from other places.

Larsen says the Asian group was in Sioux Falls one day in June and three days in July, cheating stores out of $66,000, and the team of four black males targeted Dollar General stores in Flandreau and Madison on July 18th.
