three children hurt as metal rails pierce car Police say a young family is remarkably lucky not to be more seriously injured after two metal rails pierced their car during a crash in Sydney's north, missing one of the children sitting in the back seat by just millimetres. The family's Toyota Camry had to be cut from the guard rail following the crash in West Pennant Hills about 2.20am on Tuesday. The children - aged one, three and five - were taken to The Children's Hospital at Westmead, one with a suspected fractured arm and another with facial injuries, but they all are expected to make a full recovery. Police say the children, who were all sitting in the back seat, could have been killed when two metal rails penetrated their vehicle. "They have had a very lucky escape this morning," a NSW Police spokeswoman said. The poles have penetrated straight through the car and just missed one of the children by literally millimetres. The young girl who narrowly missed being struck in the head as she sat in her booster seat is believed to have been grazed on the face. Police said the children's mother, aged in her 30s, was driving at the intersection of Eaton Road and Pennant Hills Road when the vehicle crashed into the guard rail. The mother was breath-tested at the scene and returned a negative reading. She was not seriously injured. Officers from Eastwood Local Area Command are investigating the cause of the crash. Anyone who saw the crash should call Crime Stoppers on 1800 333 000.
