A 14 year-old boy stabbed a 16 year-old girl about nine to 11 times at an Oklahoma high school assembly because she didn’t want a relationship with him beyond friendship, authorities told the Oklahoma County District Attorney’s Office on Friday.

The teen stabbed his fellow student earlier this month at Luther High School, but details on the name of the assailant and his victim have not been released, since they are minors, according to the Oklahoman. The girl didn’t see the boy as he moved to a seat behind her at the assembly. Then, silently, he stood up and began stabbing her with a 4-inch folding knife, creating wounds in her arm, upper back, wrist, and head, KFOR reported.

The girl has been released from the hospital and is “doing fine” authorities toldKOCO. Her assailant is in the Oklahoma County Juvenile Detention Center and his bail is set at $50,000.
