A horrified woman claims she found a spy camera in a clothes store fitting room.
The unnamed shopper spotted a device near the mirror.
It is almost the same colour as the wall and is barely noticeable.
She was joined by a male companion, who dismantled it.
The pair claim it is a wireless screw spy camera that was fixed to the wall with tape.
The shocked shopper posted the video on TikTok, where it has got 21.5 million views.
She alleged: “Girls, this happened to me in a fitting room.
“I was about to try something on when I noticed a strange screw with tape, really weird.
“Be careful because it’s clearly someone who set up these hidden cameras.”
The woman said it happened at a shop in Culiacán, Mexico.
Shocked viewer Natashia asked: “My question is, what do they do with those recordings?”
And another warned: “Every time you go to a store, make sure to check the fitting room.”
