10-year-old dies under elevator at school for disabled children

St Lucy's School will remain closed today after a 10-year-old boy was killed on Wednesday after becoming stuck under an elevator at the school on Sydney's upper north shore.

The school for disabled children in Wahroonga called emergency services around 2pm when they discovered the student stuck under the lift and seriously injured.

Fire and Rescue NSW were unable to rescue him and he was pronounced dead at the scene. Police have since established a crime scene and performed a recovery operation.

The Catholic Dominican school notified parents soon after the event and posted a statement on its Facebook page Wednesday night.

"St Lucy's School is very sad to confirm the tragic death of one of our students," St Lucy's wrote.

"We are cooperating with investigating police.

"We ask for privacy and space for our students, families and staff to grieve at this difficult time as we remember our beautiful student."

It is unknown how the boy got under the elevator or became trapped. Police are continuing their investigation today and will prepare a report for the coroner.
