Portland, OR -

The Oregon Court of Appeals has ruled that a 12-year-old boy was compelled to confess to a sexual-assault charge by two plainclothes police officers.

The appeals court decision issued Wednesday clarifies the circumstances under which such interviews with juvenile suspects take place.

The court found that the detectives created a "police-dominated atmosphere" when the sixth-grader's principal brought him to an interview room with just the two officers, who questioned him for more than 90 minutes.

The boy's attorneys asked that the confession in the interview should be suppressed.

A Multnomah County juvenile court judge denied that request, but the ruling issued Wednesday sided with the boy's attorneys. His parents weren't notified of the interview.

The case was sent back to juvenile court.
