A former Hawaiian Mission Academy math teacher was charged tonight in connection with a sexual assault of a teenage girl over a five-month period three years ago.

Police said the Bryan Lindberg, 42, who now teaches at Leilehua High School, was charged with 11 counts of first-degree sexual assault and five counts of third-degree sexual assault. 

The assaults are said to have occurred at Hawaiian Mission Academy in Makiki beginning in October 2008, when the girl was 14, and continued until March 2009, police said. The victim is now 17. Lindberg taught math and computers at the private Christian school until about three years ago when he left for personal reasons, according to Principal Hugh Winn, who said police never talked to him about the case. Winn took over after the teacher left.
