A teenage boy was arrested early Tuesday, accused of raping a girl inside their Philadelphia high school last week.
The alleged sexual assault happened Friday morning at Germantown High School at Germantown and Harvey Streets, Philadelphia Police Special Victims Unit told NBC10.
The alleged incident happened during first period around 7:45 -- about 15 minutes after classes begin -- in the boiler room in the basement, school district spokesman Fernando Gallard told NBC10 Tuesday.
The suspect and victim -- both freshmen -- were talking before the attack, SVU Police Capt. John Darby said a press conference Tuesday afternoon.

"At some point the male proceeds down that stairwell to a basement area, the female follows him," Darby said. "Inside the basement area there we do have a sexual assault -- we have a rape of this victim."
After the alleged attack the girl alerted the principal, a teacher and school police who then called Philadelphia Police out to the scene.
A rape kit was done on the teenage girl after the incident, cops said.
The area wasn't monitored by security and should have been, the school district told NBC10.
Officials say they want to know why no one was monitoring cameras focused on the stairwell.
Neither the victim nor suspect has returned to school after the incident, officials said.
The boy faces a slew of five felony and four misdemeanor charges including rape, sexual assault, unlawful restraint and related charges.
