More retailers were warned that pizza doughs may be unsafe to sell as a man suspected of putting razor blades in dough sold at the Hannaford store in Saco, Maine, was scheduled to appear in a New Hampshire court Tuesday.

Nicholas R. Mitchell, 38, was arrested Sunday night and charged as a fugitive from justice in Dover based on an arrest warrant from the Saco Police Department. Saco police have not said what charges Mitchell faces for allegedly putting razor blades in pizza dough at the local Hannaford.

Authorities have not said what might have motivated the crime, although Mitchell is a former employee of the Scarborough company that makes several brands of dough, including Portland Pie Co. The chief executive of the dough maker said on Monday that pizza dough sold by other retailers may also have been affected.

Saco police cited reports that pizza doughs had been tampered with at other supermarkets in the region, suggesting the suspect may have traveled to other stores in Maine and in other states.

No injuries or illnesses have been reported in connection with the malicious tampering case.

Mitchell remained in custody at the Strafford County Jail in Dover on Monday and declined a request to be interviewed.

A customer at the Saco Hannaford’s found razor blades in Portland Pie pizza dough purchased at the store on Oct. 5. But the police investigation widened in subsequent days, and on Sunday Hannaford issued a product recall for all Portland Pie dough and cheese products sold at its 184 stores in New York, Massachusetts, Vermont, New Hampshire and Maine.

The recall is retroactive to Aug. 1, according to Hannaford spokeswoman Ericka Dodge.

Hannaford has not said how many malicious tampering incidents have been reported or where they allegedly happened. Dodge referred all questions about the incidents to the Saco Police Department.

Portland Pie branded products are supplied by It’ll Be Pizza, which operates a manufacturing facility in Scarborough that provides dough to retail pizza shops, supermarkets, schools and restaurants in every state in New England and beyond, according to the company website.

Saco police said Mitchell is a former employee of It’ll Be Pizza, but would not say how long ago he worked there or provide details about the circumstances of his departure.

Mike White, CEO of It’ll Be Pizza, released a statement on Monday confirming Mitchell is a former employee of the company. He also said the incident “has no direct connection to the Portland Pie Co. restaurants or to any of their menu items.”

White said the company has been working with law enforcement and retail supermarket partners. He indicated other retailers may be affected and there may be further recalls.

It’ll Be Pizza has reached out to its other retail distributors to recall products as Hannaford has done, he said. White did not name those retailers. The Portland Pie Co. products made by It’ll Be Pizza are sold at Hannaford, Shaw’s and Big Y Supermarkets, according to the company website.

No additional recalls by other retailers had been announced Monday.

“Due to the ongoing nature of the criminal investigation, we cannot make further comment at this time,” White said in the statement. “We remain committed to our customers, our distribution partners and to the continued excellence and safety of our products.”

Saco Deputy Chief Corey Huntress said Monday that additional tampering incidents have been reported in Dover and in Sanford, Maine.

Sanford police did not respond Monday to requests for information about possible food tampering incidents in that city.

Lt. Brant Dolleman of the Dover Police Department said Mitchell is not facing any local charges related to food tampering. Police in Dover have heard rumors of tampering, but no incidents have been reported, he said.

Anyone who believes they purchased food that has been tampered with should call police, Dolleman said.

“I want people to be aware, but I don’t want people to be terrified,” he said.

Mitchell was arrested around 6:30 p.m. Sunday at a house in Dover. He remains in custody at the Strafford County Department of Corrections and is expected to make his first court appearance Tuesday morning in Dover.

Hannaford said the recall timeline includes all Portland Pie pizza products purchased between Aug. 1 and Oct. 11.

Customers who purchased Portland Pie pizza dough and Portland Pie cheese at any Hannaford deli between those dates should not consume the products and may return the product for a full refund. Customers are also being urged to check storage areas, including freezers, for product that may have been purchased during that timeframe.

Mitchell is currently on probation in Maine after pleading guilty in September 2018 to one count of criminal threatening with a dangerous weapon, a felony, according to the Maine Department of Corrections and the State Bureau of Identification, which holds criminal history record information. Details of that case were not available Monday.

Mitchell was sentenced to two years in prison and two years probation, with all but seven days of the custodial sentence suspended, the records show. He was last listed as living in the Biddeford area, but also has ties to Sanford, according to the records.

Mitchell also was charged with theft in 2018, but he pleaded to another charge not specified in his criminal history record and he was ultimately fined $500. He has one pending case in York County from May, when he was charged with violating the conditions of his release.
