From live scorpions to threatening notes, fast fashion retailer Shein has become notorious for sending unwanted items with its packages. But one customer says there was something more nefarious in her recent order.

In a video with over 4.3 million views, TikToker Riya (@bandanabixch14) shares a clip of her wearing overalls that she recently purchased from Shein. She squeezes the back panel of the clothing, which produces a beeping noise.

“I’m so scared right now,” she says. She takes a knife and slices the denim open to see what is making the beeping noise.

She pulls out a circular, white tab with the word “Chipolo” on it. “What the [expletive] is this?” she asks. The on-screen text reads, “So I found a tracker in my overalls from Shein.”

In the caption, Riya writes, “What y’all missed was the panic attack and the police report but I’ve had these for a lil while now and I had no idea bro. I feel so violated.”

According to the manufacturer’s website, Chipolo is a tracking chip similar to the Apple AirTag. Users can attach the chip to their belongings and track their location through an app.
