A New York City teenager who was involved in taking a subway train for a joyride in January has been arrested again, this time for stealing MTA equipment, police say.

A Bronx teen was arrested for allegedly operating an empty subway train in Brooklyn and faces charges including reckless endangerment. He has a history of arrests and was caught possessing MTA gear at his school.

Cops arrested a 15-year-old Bronx boy Thursday who’s been linked to as many as eight subway and rail yard break-ins — including taking a stolen subway R train on a dangerous joyride. The youth — who is not being named because he is a minor — sparked suspicion Thursday morning after setting off a metal detector at Alfred E.
