High-interest lender will leave Mass.

An Internet-based payday lending company that was accused of selling loans at up to 600 percent interest — in violation of Massachusetts law — will no longer be able to do business in the state under a settlement with the attorney general’s office.

Under the agreement, announced yesterday, Albuquerque, N.M.-based FastBucks will return at least $35,000 in fees and interest charges to Massachusetts consumers. It will also make a $10,000 payment to the state. In addition, the company will cease all collection efforts.
