Authorities say a 12-year-old boy was seriously injured when a massive sand tunnel he was building at a central New Jersey beach collapsed on him.  In addition to that, a firetruck racing to the scene hit a pedestrian and a child he was holding.

Long Branch officials say the boy, identified only as an Ocean Township resident, was building the tunnel with his younger brother when it collapsed around 3:20 p.m. Tuesday. The boys' mother, who was nearby when the collapse occurred, called 911 and reported her son was covered in sand.

Emergency responders soon dug out the child and performed CPR on the boy, who was unconscious.

Details on the boy's injuries were not disclosed. But authorities say he regained consciousness after being taken to a hospital, where he was being treated in the intensive care unit on Tuesday night.

Meanwhile, a Long Branch firetruck speeding to the scene hit a man holding an infant at Ocean & Madison Avenues reports the  Asbury Park Press.  The unidentified man suffered non-life threatening injuries while the infant is in a hospital intensive care unit.
