Bull sharks were released in an Arkansas river.

A screenshot of an article is spreading some unnerving news on social media — that a bunch of sharks are swimming in a river running through Arkansas. 

“Highway accident leads to over a dozen bull sharks being dumped in Ouachita RIver,” it says. “An early morning accident on Airport Road led to the accidental release of over a dozen bull sharks into the Ouachita River, one being 15 ft in length.”

The screenshot is being shared as authentic news, but if you search for the story online, you’ll find that it originated on a self-described “fake news” website.

The story was posted on the website Spa City Chronicle on Feb. 25. It’s labeled “Fake News” and details the hunt for the largest shark —  “Jaws” — who was supposedly captured attacking a small boat. 

Bull sharks are no strangers to rivers. They prefer low-salinity waters and can thrive in freshwater, according to Louisiana Fisheries, which noted that they’ve been found as far up the Mississippi River as St. Louis, Mo. 

But this story isn’t true. We rate claims that it is False.
