Caught red (pepper) handed.

A DoorDash driver has been banned from the app after being accused of dousing an order with pepper spray and causing an unsuspecting customer to fall ill after eating the tainted food.

The sick act was caught on a doorbell camera outside an Evansville, Indiana, home just after midnight on Sunday.

The driver, who hasn’t been charged with any crime, was dropping off an Arby’s delivery to Mark Cardin and his wife, Mandy, when she snapped a confirmation photo before suddenly producing an object from her pocket and spraying the order.

The blue-haired worker placed the spray back into her jacket pocket before walking away, all in front of the camera.

The couple brought the order inside, unaware that something was wrong with it and began chowing down.

Moments later, Mandy began struggling to breathe.

“I noticed my wife had starting eating and she started choking and gasping, and after she had a couple bites of her food she actually threw up,” he told WFIE.

The horrified customer began investigating the cause of his wife’s sudden illness when he examined the order.

“I had a look at the bag and seen that there was some kind of spray or something,” Cardin said. “The bag had been tampered with. So I pulled up my doorbell camera and seen that the lady who dropped the food off had actually tampered with it on purpose for some reason.”

Cardin shared the photos and videos of the driver to Facebook asking for help in identifying the driver.

He attempted to contact her but found she already blocked him on the app.

Cardin reported the food runner’s stunt to DoorDash and the Vanderburgh County Sheriff’s Office is looking to get the driver fired and charged.

“I definitely want to see her prosecuted,” Cardin told WFIE, adding that they had never met her before and had left a tip before the incident.

The driver has been banned from the app after footage surfaced of the late-night delivery.

“We have zero tolerance for this type of appalling behavior. The Dasher in question has been permanently removed from the platform, and our team is standing by to support law enforcement with any investigation,” a DoorDash spokesperson told The Post.

Cardin doesn’t know exactly what was sprayed on the food, fearing it could’ve been worse than it was.

“It’s horrific,” Cardin said. “We assume it’s pepper spray, that’s more than likely what it is, but now in this day and age it could’ve been anything. It could’ve been rat poison, it could’ve been fentanyl. I mean, my wife could’ve been dead.”

The Vanderburgh County Sheriff’s Office has opened an investigation into the driver and could charge her with consumer product tampering, a level 6 felony, according to WFIE.

If the foreign spray resulted in harm the charge could be increased to a level 5 felony.

“We live in a terrible world right now,” Mark said. “Horrific. People are mean for no reason. There was no reason to do what she done,” Cardin said, encouraging other food delivery app users to be cautious with their future orders.

“I would say to anybody, if you order food on any kind of delivery service, make sure you have a doorbell,” Mark said.

“This is making me second guess ever ordering food from anywhere ever again,” he said.
