The person responsible for putting razor blades inside several Portland Pie Pizza doughs has been arrested, according to Saco police.

Nicholas R. Mitchell, 38, is a former employee of the Saco-based It’ll be Pizza company, which manufactures products for Portland Pie. He was arrested in Dover, New Hampshire.

Store security surveillance footage revealed a person — later identified as Mitchell — who tampered with the packaging of several Portland Pie pizza doughs, police said.

The tampering came to light after a customer at the Saco Hannaford Supermarket purchased a Portland Pie Pizza dough and found razor blades inside of it on Oct. 6.

Saco Deputy Police Chief Corey Huntress said that Mitchell will have to be extradited back to Maine. It’s unclear what charges he will face, or if he was represented by an attorney.

Hannaford Supermarkets expanded its previous recall Sunday night “out of an abundance of caution,” according to the company.

The recall is for all Portland Pie cheese and fresh dough sold in the deli department and Hannaford has removed all Portland Pie branded products from its stores in New York, Massachusetts, Vermont, New Hampshire and Maine.

Customers who purchased Portland Pie pizza dough and cheese between Aug. 1 and Oct. 11 should not eat them and may return them to the store for the full refund, the company said.

Police asked that anyone who found razor blades inside Portland Pie Pizza dough call the Saco Police Department’s Detective Division at 207-282-8216.
