(AP) — The Nebraska Attorney General’s Office has issued a consumer alert to warn Nebraskans of a scam in which callers claim to represent Nebraska law firms collecting outstanding debts.

Attorney General Jon Bruning said Friday that residents should be mindful if they receive a call demanding payment for an unfamiliar debt.

Bruning says consumers receiving such calls should ask questions and request information in writing. Residents should never wire money or send prepaid debit cards to someone they don’t know.

In the past 30 days, the Attorney General’s Mediation Center has received 26 Nebraska-based complaints regarding fraudulent debt collection calls. The Nebraska Bar Association also has received reports of complaints from out-of-state consumers receiving scam calls from those claiming to represent Nebraska law firms.
