A coach at Bainbridge High School is under investigation for alleged inappropriate contact with a BHS student, officials with the Bainbridge  Island School District announced Friday.

The coach is also a teacher at Sonoji Sakai Intermediate School.

District officials did not identify the teacher, but said in an announcement and a letter to parents that “there was sufficient concern that the teacher violated the district policy regarding staff/student boundaries, and the policy prohibiting sexual harassment.”

District administrators learned of the allegations on Tuesday, July 12.

Police were notified the same day, officials said.

“We are deeply concerned about these allegations as it is our goal to protect students and maintain a school environment that supports students’ physical, emotional and academic growth,” District Superintendent Peter Bang ­Knudsen said in a statement. “We are assessing our training protocols and reviewing and revising, as necessary, our policies and procedures to better ensure student safety.”

­“This is a difficult time for all of us and we thank the community in advance for its support and understanding,” he added.

The allegations involve only one student, district officials said.

The teacher was placed on administrative leave on Thursday, July 14.

Officials said the school district was cooperating with the police investigation, and had also hired an independent investigator to conduct an internal investigation.
