STATEN ISLAND, N.Y. -- An autistic teen suffered leg fractures, needs a wheelchair to get around and is looking at surgery after being thrown to the ground in an "Ultimate Wrestling move" by an assistant dean at South Richmond High School, his parents allege.

Brian Shane, 15, of New Springville, is in "extreme pain" with a double leg fracture as a result of the Monday morning incident, which was triggered by a pushing match during a ball game in gym class, said his father, David Shane.

Shane said it’s the fifth time in two years that his son has been physically assaulted by fellow students, with injuries culminating in a concussion, an eye injury and stitches.

"It’s been a nightmare for my son," said Shane.

He said administrators at the school, situated on the grounds of Mount Loretto, have been unresponsive and said the city Department of Education (DOE) has ignored their pleas to have Brian transferred.

In the latest incident, Shane said Brian, who is "highly functioning autistic," was verbally harassed by two boys who then began pushing and shoving him. Shane said Brian "started to protect himself" when the dean "grabbed Brian around the chest and wrapped his leg around Brian’s leg. They both flew backward in what my son said was like an Ultimate Wrestling move."

Shane described the dean as 6-foot-2, 400 pounds.

Brian is 5-foot-10, 175 pounds.

When Brian was unable to get up, school authorities called 911 and alerted the family that an "incident" had occurred. An ambulance transported Brian to Staten Island University Hospital, Ocean Breeze, where doctors told the family his left leg had been fractured in two places. He was given crutches, told to use a wheelchair and advised he will likely need surgery.

Shane said principal James McKeon and one of the school’s assistant principals went to SIUH to talk with the family and hear Brian’s side of the story.

"He listened and shook his head and said ‘I’m sorry this has happened,’" recounted Shane. "He also said, ‘We will arrange for home instruction.’ He spent about 20 minutes."

McKeon declined comment to the Advance, referring questions to DOE. A spokeswoman there was unable to immediately comment.

"My son is really uncomfortable," said Shane. "He is normally stoic, but he is in an extreme amount of pain. He is scared. Every day he begs us not to send him to school."

Shane said DOE has declined a safety transfer of his son to another school.

"My son plays hockey and now his hockey season is shot," said Shane of the red-headed teen.

Shane, a retired FDNY paramedic, said his family is already having health insurance problems, including coverage for the wheelchair. He said his insurance company told him the school should cover the cost, but said the school told him that was not the case.

Meanwhile, Shane has retained the firm of D’Agostino & Associates, Eltingville, which today filed a $5 million personal injury lawsuit against the city.

And Shane said he and his wife, Mary, a nurse, are more convinced than ever that they will relocate to Toronto, Canada, once their house here, currently on the market, is sold.

"They put more of an importance on education for everyone there," said Shane of Canada, where he and his wife have family roots. "There my son will be able to play hockey as much as he wants."
