A Pennsylvania man suspected in connection with a terrifying home invasion was tracked down by police using his alleged victim’s AirPods.

Nafis Fisher, 33, was arrested after two police departments worked together to find the person responsible for entering a family’s home in Upper Southampton early Tuesday morning. According to a press release from the Bucks County District Attorney’s Office, the suspect entered the home where a mother, a father in hospice care, and their 25-year-old daughter were asleep. The daughter told police that she woke up to an unknown man “restraining her on her bed.”

The daughter started screaming, which woke up her mother, who encountered the suspect and “briefly grappled” with him before he fled the home with several items.

One of those items was a pair of Apple AirPods.

Police responded to the home at 2:47 a.m. and identified the missing items. During their search, the DA stated, they found a “large kitchen knife” in the daughter’s bed and a 12-foot extension cord that police believe the suspect brought with him to restrain her. During a press conference, Bucks County DA Jennifer Schorn stated that “it was quite clear that he was targeting the 25-year-old victim’s bedroom.”

She added, “If [someone] unwittingly provided information to [the suspect] to allow him to target this victim and their family, it is incumbent upon that individual to share that information now. It would certainly be better for them to find us than us find them.”

Neighbors told police that they saw a black sedan drive away from the family’s home after seeing him run out of the house.

When police realized that AirPods could be tracked using Apple’s Find My app, they used the app to attempt to locate the AirPods in hopes that it would lead them to their suspect. According to the DA, police were able to follow the suspect’s movements until the tracking stopped at a location in Philadelphia.

Officers with the Philadelphia Police Department soon located a black Kia Forte sedan. When an officer with the Upper Southampton Police Department activated the AirPods remotely, it emitted a signal that came from the direction of the car. Sleeping inside the car was Fisher, along with the allegedly stolen items from the family’s home.

Fisher was arrested and charged with several felonies including burglary, aggravated assault, robbery, criminal trespassing, theft by unlawful taking, receiving stolen property, and simple assault. He was booked into the Bucks County Correctional Facility on $250,000 bail.
