A teenage couple were arrested just 20 minutes after they mugged a man in Central Park — thanks the “Find My iPhone” app and NYPD-issued smartphones, according to police.

The two 15-year-olds came up behind a man walking home through the park near 96th Street and East Drive at about 7:30 p.m., according to Captain Peter Andrea, commander of the Central Park Precinct.

“Give me all your stuff, your wallet and phone,” the boy allegedly told the victim after lifting the ski mask he was wearing away from his mouth so he could be heard.

He then pulled up his shirt to display a semi-automatic handgun in his waistband, Andrea said.

The clueless Bonnie and Clyde fled with the 37-year-old’s cell phone and wallet, but they didn’t get far.

The victim borrowed a phone from a passerby to call 911, which immediately triggered an alert to the cell phones of officers patrolling the park, Andrea said. Cops were able to use the victim’s “Find my Phone” app to surround the suspects at 96th Street and West Drive, as they were fleeing the park.

Officers then called the victim’s phone, which was heard ringing inside the suspect’s right pocket, Andrea said.

The girl was carrying a bag containing the ski mask, wallet and gun, which was not loaded, cops said. Charges against the pair were pending Friday morning.
