SPRINGFIELD - A Hampden Superior Court judge has revoked the probation of Long Dinh Duong and sentenced him to 18 months in the Hampden County Correctional Center in Ludlow for a probation violation.

Duong was on probation for indecent assault and battery on a person 14 or over in a case in which he pleaded guilty in 2012. He was sentenced to 2½ years in the Ludlow facility with a year to be served and the rest suspended with three years probation.

Judge Richard J. Carey, after a hearing on Monday, revoked the probation and ordered Duong to serve 18 months of the suspended sentence.

The nature of the violation of probation is the fact he is charged with new crimes, specifically rape of a child by force.

The new case has not been moved up to Hampden Superior Court and is still in Springfield District Court.

In the new case Duong, 46, of Springfield, was arrested for allegedly assaulting a girl, now 17, since she was in middle school.

Defense lawyer Paul Rudof has asserted that the accusations are fabricated and rooted in a feud between the alleged victim and her mother.

According to the arrest report, Duong began sexually assaulting the victim in 2011, when she was in middle school, and continued after she entered high school. The girl's mother dismissed her claims of repeated sexual abuse and blamed her for causing trouble, the report said.

In November, after a suicide attempt, the victim told Springfield school officials about the sexual assaults. Springfield police and the state Department of Children and Families investigated and supported the girl's claim, according to court documents.

At Monday's hearing Rudof asked Carey to end Duong's probation and "let the new charges stand or fall on their own."

He said Duong has been compliant with all conditions of probation such as reporting to the Probation Department and wearing a monitoring bracelet.

Assistant District Attorney Lee Baker urged Carey to impose the 18 months for the violation of probation, saying Carey should credit the disclosures made by the alleged victim in the new case.
