Justice came slow and steady for this alleged turtle killer.

Devin Antoine Simpson, 20, was busted by cops in North Carolina for kicking to death the helpless pet — after outraged social media users saw a video of the attack online, authorities said Monday.

Viewers of the clip from as far away as South Africa figured out that it was taken in the area of Greenville, North Carolina, and alerted cops.

It didn’t help that Simpson tried to cover his tracks by taking the video of him kicking and jumping on the reptile off the web, cops said.

“The individual has since deleted the video, but it was too late,” the police said on Facebook. “Someone in the community had the forethought to record the video and send it our way.”

Simpson was arrested and charged with felony animal cruelty, the police said.

The cops thanked the public pet lovers for their assist in the arrest, saying “Thanks to you, we were able to identify the individual in the video.”

“Mr. Simpson may be smiling in his mugshot, but trust us when we say this is no laughing matter,” the post continued.
