Boy dies after quad crash on NSW farm

A seven-year-old boy has died following a quad-bike accident in northern NSW.

Two boys, both aged seven, were riding separate quad bikes at a farm near Walgett on Sunday afternoon, when one of the boys rolled his quad which landed on him, police said.

A man helped the boy at the scene before taking the youngster to Walgett Hospital where he died a short time later.

A report will be prepared for the coroner.
