A New Jersey pizza owner says he’s been the target of threats after a cop accused him of writing “pig” on her order.

The trouble started at Mancini Pizza in East Brunswick on Aug. 1, when the officer became upset over what one of the workers wrote on a pizza box for another person’s order, owner Frank Mancini said.

“My brother, using a Sharpie, put the letter ‘p’ on [the box] for plain slice and made the squiggle that signifies garlic twists,” Mancini said.

“She started yelling, ‘Why did you put pig on my pizza box, on my food.’

“So he said, ‘excuse me officer, but this is not your food, number one, and this does not say pig.’”

Mancini said that after the explanation for the writing — and after he tried to refund the officer’s money — she said “I’m having a bad day can you just give me my food,” and left.

But the incident didn’t end there. The officer’s local PBA put out a statement blasting the pizza shop, calling what happened “an affront to the officer involved.”

After word of the incident became public, the pizzeria has been under siege.

“We’ve been getting a lot of threats,” Mancini said. “People saying harmful things,”

On Yelp, user Michael D. wrote “Disgrace. They should close up shop now! Never coming back from this! BLUE LIVES MATTER.’’

Mancini has put the box in his store window to try to show the whole thing is much ado about nothing.

He also has been frantically calling cop friends to try to sway them into believing his story.

“This has been a nightmare,’’ he said. “We love cops. People just want to blow it up for our business to fail.”
