District police are investigating possible inappropriate contact between a Dunbar Senior High School student and a staff member.

D.C. Public Schools officials say they were notified of a report on Thursday of "inappropriate conduct" that took place last fall. The staff member has been removed from Dunbar while police investigate the allegations, and counseling and support have been made available for students.

"You have my commitment that we will do everything possible to ensure that Dunbar is an environment where all students can learn and teachers can teach," Principal Stephen Jackson said in a letter to parents.

This is the latest installation of a tumultuous year for Dunbar: In November, five students were charged with sexually assaulting a female student in an untended stairwell; charges were later dropped. But after observing lax security at the high school, Interim Chancellor Kaya Henderson removed Friends of Bedford, the New York-based privator operator Michelle Rhee had hired, and reinstated Jackson as principal.
