BRIDGEPORT, Conn. (AP) A federal lawsuit says officials at the exclusive Indian Mountain School in Salisbury did nothing as students were sexually assaulted and blackmailed into keeping silent.

A former student claims in a lawsuit filed Thursday he was sexually abused and assaulted dozens of times by three school officials from 1982 to 1984.

Mark Devey, Indian Mountain's head of school, said administrators recently notified the school community they are investigating to identify alumni who were victims while students.

He says the school is taking the allegations very seriously.

A federal lawsuit was filed in October by another former student who claims routine abuse of students at the hands of staff, including sex assaults by the now-deceased headmaster.

Indian Mountain School is a private boarding and day school for children in kindergarten through grade 9.
