COBB COUNTY, Ga. -- Police have charged a Cobb County music teacher with sexually assaulting a student.

Officials arrested Steven Parkman, 32, the director of the orchestra at Harrison High School. Cobb County officers arrested him late Monday afternoon.

Authorities said the victim is a 17-year-old student at Harrison High. Officials told Channel 2's Ross Cavitt that the case against Parkman is not a rape case.

"If you look at the definition by code section of sexual assault, a person commits that crime when such person has supervisory or disciplinary authority over another person. So because she was a student at the school and he was a teacher, it makes that the appropriate charge," said Officer Cassie Reece with the Cobb County Police Department.

In addition to being the director of the orchestra at Harrison High, he is also the chairman of the Fine Arts department at the school and was named the STAR Teacher for the 2007-2008 school year.

Parkman was released Tuesday morning on a $35,000 bond.

A spokesman for Cobb County Schools, Jay Dillon, says Parkman resigned from his job Friday.
