Dung nabbit!

After three weeks of discovering stinky piles in front of her workplace, a public relations pro finally captured the crappy culprit in the act Monday, according to surveillance videos posted on Daily Mail.

Go figure: It’s just another in a long line of defecating fitness enthusiasts, ranging from the original “Poo Jogger” of Australia to Colorado’s infamous “Mad Pooper.”

This time out, the mystery squatter is a blonde in pink running gear.

“It’s disgusting — human feces shouldn’t be on the street,” said Roxy Jacenko, director of Sweaty Betty PR in Sydney, Australia, which is located on a block that’s “lovely and full of terraces and happy children.”

A neighbor, who wished to remain anonymous, told AAP there had been four or five “human stools” in the same spot over the past three weeks.

Jacenko, 39, originally posted the videos to her Instagram, where she has 246,000 followers, in hopes that the public could help identify “the perpetrator.”

“If you have any information on who this person is please contact us,” the publicist captioned the post of the pooper. Jacenko told the Daily Mail she has already received several messages about the culprit.

If caught, the pooper faces a possible penalty of three months in jail and a $660 fine, the maximum sentence in New South Wales, the UK outlet reported.

There is a prevalence of gastrointestinal problems among serious runners, according to a US study of 221 male and female endurance athletes, published in the US National Library of Medicine.

When the OG “Poo Jogger” was busted in 2018, Royal Melbourne Hospital’s director of gastroenterology, Dr. Geoff Hebbard, said vigorous exercise and colonic activity were related.

Jacenko, however, showed no sympathy for the s–tty side effects of running.

“The fact is no one should have to walk through or past human feces to enter their home or place of work,” said Jacenko. “We will be hosing away today’s mess tomorrow … I think I would hose her given the chance!”
