Michigan’s Attorney General sent cease and desist letters to a pair of businesses in Rockford, Michigan who were marketing a phony “Coronavirus Defender Patch.”

Dana Nessel’s office says the letter was issued on Tuesday to the two related businesses who claimed the product would protect people from contracting COVID-19. The companies were charging $49.99 for the patches and have been instructed to provide information for those who bought patches.

Nessel’s office says they have also received more than 1500 complaints of price gouging.
