BATON ROUGE - Deputies arrested a man for allegedly placing a tracking device on the underside of a woman's car. 

According to the East Baton Rouge Sheriff's Office, deputies responded to a call in which a woman stated there was an "unknown object" on the underside of the rear-passenger side of her car. She removed the object, which deputies determined to be a Spytec GPS tracking device. 

A product page for the device describes it as a "wireless battery-powered tracker that can be placed virtually anywhere." 

Corey Vaccaro, a Baton Rouge-based private investigator, says tracking devices like the one used in this case are typically difficult to detect, but easy to obtain. 

"For tracking devices it's very hard for the average person to find out. Very hard. You have to know what you're looking for," Vaccaro said.

Investigators were able to trace the purchase of the tracker back to Austin Henrikson, 29, using his credit card and the phone number associated with the device. 

Henrikson was arrested Tuesday and booked for the prohibited usage of a tracking device. His bond has not yet been set.
