nitial investigations showed that a former student at the Judge Rotenberg Education Center allegedly called in orders for electric shock treatments on Aug. 26 and officials at the school self-reported the prank call and unnecessary treatments the day after they occurred, Cindy Campbell, a spokeswoman for the state Department of Early Education and Care, said Monday

After the call, the teens, ages 16 and 19, were awakened in the middle of the night and given the painful shock treatments, at times while their legs and arms were bound. One teen received 77 shocks and the other received 29.

The school treats people with a wide variety of behavior problems, including autistic-like students who have aggressive, self-injurious or destructive behaviors and high-functioning students with psychiatric or emotional problems, according to a description posted on its web site.

Campbell said the school has submitted a corrective action plan that is now being reviewed by the agency.
