Greg White, 34, of Blountville, was lodged in the Kingsport City Jail after his arrest. Kingsport Police Department Detective Greg Lane said he conferred with school officials prior to making the arrest on school property.
"As a courtesy to the school, we went to the principal and explained what we had and took (White) into custody at the school," Lane said.
As the investigation continues, White is suspended from the school system with pay, Sullivan County Board of Education attorney Pat Hull said.
According to Lane, White worked with the band in addition to his teaching duties and gained access to the band booster checking account. He is charged with two counts of forgery for allegedly passing two checks in the amount of $400 each, and one count of theft over $500.
Lane said White is also under investigation in Bristol, Va., for allegations of embezzling nearly $5,000 on the same account.
Hull said the school system's full course of action is unknown at this time.
"He (White) has been suspended with pay for a period of time until the school system can get more information, which is a fairly routine thing," Hull said.
"Anytime law enforcement was involved, obviously, the school system would sort of need to take a back seat there and not interfere with the investigation that they were doing," Hull said.
"They (law enforcement) will do their thing, and then we'll get what we can from them and do our own (investigation). ... I don't think we know a great deal. The suspension was probably thought to be necessary under the circumstances until we can get more information and clear the air," Hull said.
Prior to being hired by the county school system, White worked for the Sullivan County Sheriff's Office for 11 years, most of that time as a deputy.
