The teen arrested Thursday for allegedly firing shots into a subway car and injuring two boys at a North Philadelphia station was a student at Upper Darby High School, according Upper Darby Police.
Police Superintendent Michael Chitwood told NBC10 that Darryl Lanier, 15, was a sophomore at Upper Darby High School.
Lanier was allegedly arrested at the high school the day before the shooting on marijuana charges, the Delaware County Daily Times reported.
The accused shooter turned himself in to South Detectives Thursday with the help of his parents. He was wanted for opening fire inside SEPTA Broad Street Line car at the Susquehanna-Dauphin Station and injuring a 14-year-old and a 17-year-old.
Police say surveillance video caught Lanier arguing with two people inside the subway car before the shooting.
Neither of the teens shot were involved in the argument. The 17-year-old was treated and released. The 14-year-old is in critical condition.
Lanier was charged as an adult on Friday. He is charged with Attempted Murder, Aggravated Assault, Burglary and other related offenses.
Lanier was arraigned with bail set at $2 million. He is scheduled for a preliminary hearing on October 5.
