A 13-year-old boy is dead after a longboarding accident in southwest Calgary Tuesday.

Police were called to the 100-block of Millrise Boulevard just before noon.

Investigators say the boy struck a cable on a fence.

The boy was wearing a helmet at the time, but his larynx was crushed in a fall.

An off-duty paramedic was first on scene and gave first aid to the boy until EMS arrived, police said.

"The injuries that we heard from the scene is that he had catastrophic injuries to his neck," Staff Sgt. John McCarthy said. 

The boy died as he was was being taken to Rockyview General Hospital.

This tragic accident comes as the boy was set to go back to school Tuesday. 

Michelle Russell, whose daughter is close friends with the boy, said many of the children who knew him are having a difficult time with the news.

"The kids are all so sad to hear what happened to him," Russell said. "The thought of going back to school is hard now."

Police say victim services is with the boy’s family and will work closely with his friends.

Laverne Schaffer, who lives in the neighbourhood, says kids come down the alley where the accident took place on skateboards and longboards every day.

He would like to see some changes made to increase safety.

"I hope something can be done about it," he said. "Bring minds to bear that can solve the problem and find a way to keep it from happening again for sure."
