MIDDLE TOWNSHIP, N.J. (AP) — A young Pennsylvania boy was seriously injured when a basketball hoop support pole broke and fell on him at a southern New Jersey playground.

Witnesses said the 10-year-old — identified only as a Philadelphia area resident — was hanging on the hoop’s rim when it broke around 6:45 p.m. Saturday at the Grande Woods Trailer Park in Middle Township.

Authorities told The Press of Atlantic City that the boy sustained a serious chest injury and facial lacerations.

He was flown by helicopter to Cooper Medical Center in Camden, where he remained on Sunday.

Further details on his injuries were not disclosed.
