A former Bristol, Tennessee teacher was arraigned in Sullivan County criminal court this morning.

Randy McCoy is accused of the sexual exploitation of a minor. The charges were placed after more than 450 images of child pornography were found on McCoy's home computer.

Prosecutors tell us they have filed a motion asking the judge to increase McCoy's bond.

He will be back in court on April 12.

McCoy is a former teacher and band director at Vance Middle School.
