She caught a potential predator — on camera.

A 17-year-old girl shared the creepy moment an older man allegedly harassed her at a thrift store — and even invited her to his house despite her informing him she was just a teen. A video depicting the “To Catch a Predator”-esque encounter currently boasts 2.5 million views on TikTok.

“There are creeps out there everybody please stay safe,” reads the caption to the video public service announcement, which was uploaded by Nova Scotia native Jaycie Crouse.

She explained that she “started recording because this man was being sus” — TikTok slang for suspicious.

The retch-worthy footage, reportedly taken while Crouse was perusing a thrift store by herself, depicts the adult man approaching the youngster in a store aisle and commenting that she’s “one of the most beautiful girls he had ever seen.”

He then asks if he can buy her something, which Crouse turns down, as seen in the footage.

Undaunted, the shady character then proceeds to ask if she’s engaged or single, prompting the aghast gal to inform the lech she’s just 17 in the hopes of deterring his advances.

Unfortunately, the fact that Crouse was underage only seemed to encourage the creeper, who commented “that’s a good age to be” in the recording. He then asked the petrified shopper if she’d like to work for him around the house as he has a bum knee.

“I got injured about a month or so ago, my knee is kind of banged up,” described the senior, adding that injury has caused him to fall behind on his work. He explained that he was “looking for someone to do stuff around the yard,” among other things.

Thankfully, the quick-thinking gal was able to end the creeptastic encounter by claiming she was getting a phone call and had to go.

The spine-tingling situation sent shudders through TikTok.

“Oh my god that is terrifying, it’s very sad a lot women are hit on when they are younger and look young,” said one aghast gawker.

Another wrote, “A grown man would never ask a woman, let alone an underage girl, for help with something physical. Remember that girls!! Immediate red flag!”

Others even compared the situation to serial killer Ted Bundy, who notoriously feigned a broken arm to lure his victims.

“Ted Bundy used a tactic where he would wear a cast to make himself seem non-threatening and vulnerable to lure ppl in, and this guy with his knee…,” explained one TikTok true-crime pundit.

One horrified poster wrote, “If he kept talking to you after you said you were 17 imagine the day he asks someone younger who doesn’t know better to go to his house w him.”

Crouse replied, “Exactly that’s why I posted it.”

This isn’t the first time a TikToker has caught a creep on camera. Earlier this week, a 21-year-old Australian gal surreptitiously filmed a voyeur taking pictures of her as she sunbathed on the beach.
