Ammon News - A mechanic has gone viral on TikTok after he recalled an unusual incident he had at work, after a worried woman brought her car in for a checkup at the garage.

A mechanic’s distressing video showing how a woman allegedly had a secret tracker installed on her car by an ex-boyfriend has been viewed more than 1.8 million times.

The clip has served as a warning to others, who commented to thank the man for taking her worries seriously.

TikTok user @ kaos_noe, shared the video with the caption “What the F…” two days ago.

In it, he says: “So a customer is scared there’s a tracker in her vehicle from a crazy ex-boyfriend.”

He then shows himself under the vehicle looking at the car’s underside, where he discovers a small device near the wheel.

He says: “What the heck?” incredulously and scans the QR code on the device, before searching a number associated with it online.

The post racked up more than 300,000 likes and thousands of comments.

There have been no updates on the post and it's unclear if the incident was reported or if any action was taken against anyone involved in the alleged incident.

People were left angry and concerned, with one writing: “Thank you for checking and not blowing it off. You might have saved her life."

Another commented: "I'm glad you found it, but never second guess a woman who suspects safety issues around an ex until it is proved safe beyond a shadow of a doubt."

A third replied: "Thank you for actually checking vs assuming she's crazy.

"This happened to my friend in college but it took her going to three places for them to check."

Another viewer asked the mechanic: "Why didn't you believe her when she said that?"

The man replied: "I didn't believe someone would actually do that.

"Everyone in the shop was just as surprised when I told them to come check this out."
