Her father, John Price, of Mobile, told WALA that his 23-year-old daughter told him she had received an alert on her cell phone that said she had been tracked on her way home from work on Thursday.

Price told the network that his daughter found the Apple AirTag on the tire wheel well of her car.

The Apple AirTag is a small device that was designed for people to place on everyday items, such as keys and cell phones, in order to keep track of them.

After Price’s daughter learned she had been tracked, she called her family and asked what she should do next.

Price said he called the Mobile Police Department (MPD) but that it was unclear who the tracking device belonged to and why it was placed on his daughter’s car.

Data from the U.S. Bureau of Justice Statistics found that there were about 3.79 million victims of stalking in the U.S. in 2016. Of those, 1.77 million had been stalked using some type of technology.

Price told WALA: “It was just one of those really scary moments for any parent to find out that your 23-year-old daughter is being tracked.”

He later said: “You never really think it’s going to pertain to you or your family until it does and then you’re like. ‘Holy cow.’ This is my daughter. Hopefully it helps somebody down the road find something that’s not supposed to be there.”

Newsweek has contacted the MPD for comment.

Apple said in a February 10 statement that it was aware of reports of “bad actors attempting to misuse AirTag for malicious or criminal purposes.”

It continued: “We have been actively working with law enforcement on all AirTag-related requests we’ve received. Based on our knowledge and on discussions with law enforcement, incidents of AirTag misuses are rare, however, each instance is one too many.”

Newsweek has previously reported on cases where women have been stalked using tracking devices.

American Mieke Oort, 21, was killed during an attack in her apartment in Leeuwarden, a city north of the capital Amsterdam, in March.

The suspect, a 27-year-old man, was detained in Germany the same month and had met Oort on a Tinder date, according to one of her friends.

Her older sister told WCVB-TV that the suspect had placed a GPS tracking device on her bicycle.

She said: “He put a tracker on her bike because in the Netherlands, you bike everywhere. Right now, we’re just trying to process this whole situation and really say our goodbyes and make the necessary arrangements that we’ll have to do.”
