SPRINGFIELD - A Springfield man being held on $100,000 bail in a child sex assault case is still on probation following a 2012 conviction for indecent assault and battery.

Long Dinh Duong, 46, of Springfield, pleaded not guilty last week in Springfield District Court to six sexual assault charges, including one count of rape of a child by force.

The alleged abuse began in 2011 when the victim was in middle school and continued after she entered high school, according to Assistant District Attorney Cary Szafranski.

The girl's mother dismissed her claims and blamed the victim for causing trouble, the prosecutor said.

The new charges will likely complicate Duong's probation status from a 2012 conviction for fondling a coworker at an Agawam book binding company.

Following a two-day trial, a Hampden Superior Court jury found him guilty of one count of indecent assault and battery on a person over 14.

Duong, a registered Level 1 sex offender at the time, had denied grabbing the breast of a co-worker at the Bridgeport National Bindery in April 2010.

After a jury returned a guilty verdict, a judge sentenced Duong to 30 months at the Hampden County Correctional Center, with 18 months suspended and 12 months to be served direct. In addition, Duong was ordered to serve three years probation after completing his sentence.

Following the conviction, Luong was reclassified as a Level 2 sex offender, meaning he poses a moderate risk of reoffending.

The trial was delayed in part because Duong, a native of Vietnam, spent 203 days in the custody of Immigration and Naturalization Service. That time eventually counted against his sentence, reducing his actual jail time to four months.

In an appeal, Duong's lawyer argued that he was unjustly convicted due to selective prosecution and juror bias. Filed three weeks after the trial, the appeal was rejected in July 2014.

In the current case, Duong's arraignment, scheduled for Dec. 3, was delayed one day due to a lack of a Vietnamese interpreter.

At the hearing, he pleaded not guilty to rape of a child by force; assault with intent to rape a child; two counts of indecent assault and battery on a person under 14; and two counts of indecent assault and battery on a person 14 or over. Judge William Boyle ordered him held on $100,000 bail, and continued the case for a pretrial hearing on Jan. 4.
