A Westbrook man who was a school bus driver in Scarborough and allegedly asked a girl to send him a nude picture of herself has been charged with sexual exploitation of a minor.

Stephen C. Mitton, 47, of Saco Street made his initial appearance Wednesday in Cumberland County Unified Criminal Court on that charge, a felony punishable by as much as 10 years in prison, and a misdemeanor charge of unlawful sexual touching.

Mitton was arrested Tuesday by Westbrook police, who are continuing to investigate.

Judge Jeffrey Moskowitz ordered Mitton held on $5,000 cash bail. As conditions of bail, the judge ordered Mitton to have no contact with the alleged victim, her mother or anyone younger than 18.

The Scarborough School Department said that, though Mitton’s picture and profile are still on the department’s website, he is no longer an employee.
