L.A. County prosecutors on Thursday declined to file charges against a Christian school principal accused of lewd acts against a student, citing insufficient evidence.

Daniel Weston, 47, was arrested Tuesday by Whittier police on suspicion of inappropriately touching a child younger than 14 in a sexual manner.

The incident allegedly took place in January 2008, when he was principal of the Seventh-Day Adventist Church School in Whittier. Weston has since become principal of a church school in West Covina.

Prosecutors said the alleged victim was a 13-year-old student at the Whittier school when the incident supposedly occurred.

The alleged victim, now 17, told police the assault happened when she went to Weston's classroom and asked for help with homework.
