The fashion star didn't realise that the AirTag device had been concealed in her coat until hours later.
She only received a notification on her phone that told her an unknown item had been “moving with her for a while” and that “the owner could see its location”
Brooks (26) shared a screenshot of the notification to her Instagram Stories.
“I never share stuff like this but what the F does this mean?" she wrote, alongside the snapshot.
“This ‘device’ followed me for the last five hours to every location and was no one in my ‘network’. It also wasn't a phone or tablet, it was an ‘item’.
She later discovered that it was an Apple AirTag — a devicee designed to help keep track of keys or your wallet that often go missing.
They can be attached to various items which can then be located through using the app.
In a warning to others, Brooks pointed out that anyone could slip one into your pocket or purse and use it to track your movements.
“I never thought anything like this could happen to me and it did,” she said.
“If this does happen to you and you find an AirTag, immediately call the police and Apple to track the serial number back to the perpetrator.
“As women, we need to stick together and warn each other of situations like these."
In another Instagram post, she also shared another piece of advice.
“Another side note for my ladies, I learned my lesson the hard way,” she said. “If you're going to post at a restaurant, drinking with your girlfriends, working out, whatever you're doing — if it has a location that's obvious or geotagged, wait until you leave to post it.
“I have made that mistake so many times and it's very easily avoidable. Just wait until you're home or you're walking home or whatever until you post that.”
