Altria Group Inc said on Friday it was working with authorities to investigate if the smokeless tobacco products it recalled earlier this week were tampered with.
The company said on Tuesday it recalled some smokeless tobacco products after eight consumers complained that they found some sharp metal objects in certain cans.
The recall involved certain cans made in the company's Franklin Park, Illinois, facility.
"We believe this was a deliberate, malicious act by an individual or individuals familiar with the quality and safety procedures at its Franklin Park, IL facility", Altria said in a e-mailed statement.
The company said it was retrieving recalled product from wholesale, retail and individual consumers.
A majority of U.S. Smokeless Tobacco Company's cans made at a separate facility were not affected by the recall, Altria said.
