Robert Dacey, 49, is accused of luring two current students, now 15, to his home at various times in 2005. In addition, the indictment added a third alleged victim, who was found during the investigation. In the third case, Dacey is accused of raping and sexually assaulting a student, now 21, in the late 1990s, beginning when the alleged victim was in eighth grade, prosecutors said.
A Middlesex grand jury returned the 17-count indictment against Dacey on Thursday.
Dacey, who taught drama at the McDevitt Middle School, posted $25,000 bail last month and was placed under house arrest with an electronic monitoring device at the home of a sister in Belmont, said Melissa Sherman, a spokeswoman for the Middlesex district attorney's office. She said Dacey has since been placed in another relative's home under house arrest.
Police reports allege Dacey lured the two eighth-grade drama students to his home last year by saying that a friend of his owned a massage parlor and was trying out a new masseuse. When the boys arrived at Dacey's Waltham apartment, police say, he blindfolded them and left the room. The boys told police they then heard someone enter the room and were massaged by someone with long hair and long fingernails who they thought was a woman.
``The Commonwealth has determined and alleged that this person is Mr. Dacey," Sherman said.
Authorities allege Dacey assaulted the two eighth- graders at least nine times, sometimes together and sometimes separately, between June and November. The grand jury indicted Dacey on six counts of rape, indecent assault and battery, and enticement of a child.
The grand jury also indicted Dacey on two counts of rape of a child, one count of rape, and other charges in connection with alleged sexual encounters with a former student, who is now 21. Authorities say the sexual assaults began when the boy was a 14-year-old eighth-grader.
Waltham school officials said Dacey worked in the district for 26 years. He is currently on paid leave, according to district officials.
