Report: School district reopens investigation into Arthur's high school grades

The Dallas Independent School District has reopened an investigation into alleged improper grade changes for former star basketball player Darrell Arthur at South Oak Cliff High School, WFAA, the ABC affiliate in Dallas reported.

Superintendent Michael Hinojosa said he will ask for an outside independent review of the academic records of Arthur and his former teammates.

"There are too many questions at this time for us to just leave it alone," Hinojosa said.

Arthur, who now plays for the NBA's Memphis Grizzlies, did not respond to requests for comment.

One of the nation's top recruits, Arthur was a key player on Kansas' national basketball championship team last season.

An investigation into a grade change for another athlete resulted in South Oak Cliff forfeiting the 2006 state basketball title. The school district, however, released a report two months ago that cleared South Oak Cliff staff and students of any further wrongdoings in the 2005 and 2007 state basketball championships.

WFAA-TV's follow-up found investigators may have failed to interview witnesses and review algebra, English and theater arts grades received by Arthur.

If the district finds Arthur did not have sufficient credits to graduate from high school, Kansas could have to forfeit any or all games involving him.

Kansas athletic department officials have said they believe that the investigation into Arthur would not affect the school's basketball program.
