A Bronx co-ed has been charged with raping her female roommate at Susquehanna University, police said.

Pratigya Thakur, a 19-year-old sophomore, was arrested Monday on charges of rape, indecent assault and harassment in connection with the alleged May 16 attack at the school in Selinsgrove, according to an arrest affidavit obtained by The Post.

Thakur’s roommate reported the alleged rape to university officials May 29, then told cops June 6. She said both she and Thakur drank alcohol and smoked marijuana before the alleged attack, the arrest affidavit states.

The roommate said she was singing and dancing inside their Hassinger Hall dorm room as she packed up her belongings ahead of a move into another university housing unit for the summer when she decided to lie down on Thakur’s bed because her own was covered with clothing and other possessions, the affidavit states.

The roommate said she felt Thakur touch her but thought she was “just trying to move her” so the Bronx teen could also fall asleep in her bed, police said.

The alleged victim told police she awoke to find Thakur “on top of her straddling her” before grabbing her hands and placing them on her roommate’s breasts. Thakur then started kissing her roommate and further molesting her, the alleged victim told police.

The victim said she tried to stop Thakur’s unwanted advances, putting her arms across her body, but she felt “very intoxicated and weak,” she told police.

Thakur then asked her roommate why they hadn’t “done this before,” according to the arrest affidavit, before proceeding to slap the victim in the face and call her “b—h” and “slut.” Thakur also “kept hitting” her roommate in the face with her pelvis, the victim told police.

“Victim reports at this time she closed her eyes and tried to [be] somewhere else in her mind,” the arrest affidavit continued.

The nightmarish assault kept going as Thakur raped her with her hand, causing her to bleed, the roommate said.

A university spokeswoman confirmed to The Post that Thakur was enrolled at the school for the spring semester, completing her second year of study.

“Students who are accused of being in violation of the student code of conduct go through a student conduct judicial process, which could lead to sanctions up to and including expulsion,” spokeswoman Amanda O’Rourke said in a statement. “I cannot comment specifically on the status of this incident.”

Thakur was released from custody in Pennsylvania after posting $10,000 cash bond, The Daily Item reports.

A message left on a phone listed in Thakur’s name was not returned Friday. It’s unclear if she’s hired a lawyer.
