The owner of a Harrisburg-based Internet broadcast news site testified Tuesday before a judge examining whether the secrecy of a grand jury investigation was violated.

James Roxbury, who operates Roxbury News, appeared before Dauphin County Judge Todd Hoover for about 20 minutes, but would not comment afterward.

Roxbury was the first journalist to testify out of 15 who have been summoned to appear at the closed hearing to determine whether a special prosecutor should be appointed to investigate alleged leaks in the grand jury probe of casino owner Louis DeNaples.
