A 15-year-old Virginia boy has been found guilty of the sexual assault that led to his victim's dad being arrested and branded a domestic terrorist while protesting it at a volatile school board meeting.

Loudoun County juvenile court Chief Judge Pamela Brooks found sufficient evidence during a trial Monday to sustain charges of forcible sodomy and forcible fellatio on a 15-year-old classmate, according to ABC 7News.

The ruling is the juvenile court equivalent of a conviction for the boy, who was not identified because of his age.

Following the May attack, the teen had been transferred to another Loudoun school — where he was accused of another sexual assault on a different 15-year-old girl earlier this month.

He is due back in court on charges for that alleged sex attack, and will be sentenced for the May attack after that, 7News said.

The initial assault sparked a political firestorm in Loudoun County in June when the victim's dad, Scott Smith, was wrestled to the floor and arrested at a volatile school board meeting.

Smith's arrest was cited by the National School Boards Association (NSBA) in a letter to the White House as an example of the "immediate threat" that is "equivalent to a form of domestic terrorism and hate crimes."

Smith's attorney, Bill Stanley, told 7News on Monday that his client is still considering legal action against Loudoun school officials as well as the NSBA, despite the latter's apology Friday for some of its language.

"I am a father who cares deeply for his daughter, who would go to the ends of the earth to protect both her and other students who attend public school in Loudoun County from suffering what she has suffered due to the misguided social policies adopted by the Loudoun County School Board," Smith said in a statement.

"I am not a 'domestic terrorist.'

"The NSBA defamed me, impugning my reputation and that of other concerned parents who dared challenge our local school board.

"I am owed an apology and I deserve one," he said. "I demand the NSBA retract its statement that I am a 'domestic terrorist,' or I will have no other choice but to seek a court to do it for them."

During the trial, the girl testified that she agreed to meet the boy in a stall in the girls' bathroom, but without agreeing to sex, according to the Washington Post.

Once locked inside the stall, the boy started grabbing her even after she said she did not want sex, the court was told.

"He flipped me over," the girl testified. "I was on the ground and couldn't move and he sexually assaulted me."

The attack paused when someone came in the bathroom, only to continue soon after, the girl said.

Although the boy's attorney insisted it was consensual sex, prosecutors played interviews he gave detectives in which he admitted "messing up" and also hurting the girl.

The family's attorney, Stanley, told 7News that the Smiths were "relieved that justice was served."

"This horrible incident has deeply affected the Smith family, and they are grateful for today's outcome," Stanley said in a statement.

"No one should have to endure what this family has endured, and now their focus is completely upon their daughter's health and safety as she progresses forward with her life," Stanley said, calling the teen a "survivor and a fighter."

"The Smith family stands stronger than ever in moving forward to ensure that those responsible in the Loudoun County School system are held accountable, so that this may never happen again to anyone else's child," Stanley said.
