Milwaukie, OR -

An 18-year-old accused of sexually abusing four classmates at Milwaukie High School denies the allegations and says any sexual contact was consensual.

London Walter told KPTV he had relationships with two of the girls that became intimate.

The school sent a letter home to parents last week that said the abuse occurred between September and December 2012 but wasn't reported until February after Walter moved to an alternative high school. He was arrested Nov. 8 and is held in the Clackamas County Jail.

In the letter, the school says police asked the school to keep the matter confidential while it was under investigation.
