The unnamed walker was strolling through the streets of North Ridgeville, Ohio, at roughly 5:30am when the porky stalker started “nudging” him.
US radio station NPR has reported that the hog is called Zoey and weighs 50lbs (3.5st).
North Ridgeville Police Department posted on Facebook that a man “was being followed by a pig and didn’t know what to do”.
In a tongue-and-cheek post the force added: “A pig. Riiiight.”
The police department joked that when officers responded to the call they expected to find an “obviously drunk guy” who was “at least drunk enough to call the police on himself while hallucinating”.
But the officers were suprised to find a “very sober male walking eastbound on Center Ridge near Maddock Rd, from the actual Amtrak train station in Elyria, not the bar”.
The force added: “Oh, and he was being followed by a pig.
“Yes, a pig.
“Patrolman Kuduzovic managed to wrangle (I think this is the correct word to use) said pig into his cruiser and he is currently secured in our pig pens…..er, dog kennels. Whatever.”
Police operations officer captain Marti Garrow told NPR: “The pig was nudging the person and wanted to be petted.”
The force then posted a picture of the hairy creature in the back of Patrolman Kuduzovic’s car.
The pig has since been returned to its owner after it was collected by police on 19 May.
