A Baldwin man who was in custody Tuesday on charges of committing an armed street robbery in February was located thanks to a phone-finder app that helped investigators trace the iPhone he'd stolen, Nassau County police said.

Khalil Young, 18, of 1175 Village Ave., Baldwin, was arrested Monday and arraigned Tuesday at First District Court in Hempstead on charges of first-degree and second-degree robbery, police said. He was remanded on bail of $75,000 bond or $25,000 cash and is due back in court Thursday.

Police said three male suspects got out of a silver Audi and robbed an 18-year-old at gunpoint, taking his iPhone, near Chester and Oakley streets in Uniondale at 3:25 p.m. Feb. 12. The victim activated his phone-finder app, leading investigators to a Nassau Road barber shop. Police found the phone and were told by a witness it was bought from one of the suspects.
