An 18-year-old student at Shakopee High School was arrested in the alleged sexual assault of a female classmate on Tuesday, according to police.

The male student allegedly lured a 17-year-old female student by the wrist into a locker room during school hours before she was assaulted, Police Chief Jeff Tate said. The investigation is ongoing, and the department will release more information on Thursday, Tate said. The victim allegedly reported the incident to friends and an on-site officer, Tate said.

"With two [school resource officers] assigned to the high school, we believe it's an isolated incident," Tate said.

On Wednesday, the school district notified parents about the arrest, Tate said, which prompted police to post about it on Facebook.

The student remained in custody as of Wednesday night, Tate said.
