An aide at a state-run program for the developmentally disabled was arrested Thursday and accused of molesting one of his charges, State Police at Dover Plains said.

Dwayne Moody, a 49-year-old man from Falls Village, Conn., was charged with a felony second-degree sex act and a misdemeanor charge of endangering the welfare of an incompetent person, cops said.

Investigators were tipped off to the alleged abuse earlier in February and began an investigation Feb. 8. The probe led to Moody, who works at the Taconic Developmental Disabilities Service Office in Wassaic, a hamlet in Dover Plains.

The primary State Police investigator on the case was unavailable Thursday evening; troopers at the Dover barracks and Troop K headquarters in Millbrook declined to answer questions about the case.

Police did not say whether the alleged abuse was ongoing or whether it was a one-time incident and did not answer questions about Moody's role at the Wassaic facility.

Moody was listed as a developmental aide at the facility from 2008 to 2010 and as a direct support assistant beginning in 2011. Direct support assistants work closely with residents at state homes, doing everything from helping them dress to dispensing their medicine, according to the state's Career Mobility Office.

Moody earned $62,577 in 2011, state records show. It wasn't immediately clear whether Moody had an attorney. Calls to Moody's Connecticut home were declined by a screening service.

Moody was arraigned in Town of Amenia Court and sent to Dutchess County Jail on $25,000 cash bail or $50,000 bond.
