A girls’ basketball coach at Stonewall Jackson High School was arrested Tuesday and charged with having inappropriate relations with a minor, Prince William County police and schools officials said.

Nsonji White, 38, of the 10000 block of Woodbury Drive in Manassas was charged with five counts of crimes against nature and five counts of indecent liberties by a custodian. He is being held without bond, police said.

Police said White had inappropriate relations in 2004 and 2005 with a girl at the school who was 17 at the time. Police said the victim just came forward with the allegations.

A schools spokesman said White was hired in 2003 and works in the attendance office and as a basketball coach. He has been placed on administrative leave.

Prince William schools have reported a lengthy string of sexual misconduct cases this year. In April and May, four school employees were arrested on accusations of having inappropriate relations with students.

Ken Blackstone, the schools spokesman, said during a regularly scheduled meeting that school officials reiterated to principals the policies regarding conduct of employees in the schools.

“We have high standards and expectations for employee conduct and it’s taken very seriously,” Blackstone said. “Violations of our policy and the law will not be tolerated.”

Stonewall has been one of the Washington area’s most successful girls’ basketball programs in recent years.

When White took over as the team’s head coach before the 2004-05 season, he was the Raiders’ third coach in as many years, and the program had produced only one winning record in the previous 14 seasons.

After a 9-12 record his first year, the Raiders went 131-27 the next six, and reached the Virginia AAA playoffs four times. Stonewall advanced to the state championship last season and lost to Princess Anne.
