Is this sentence using ‘had been found sitting’ acceptable? <br/><br/><i>Cathy said her son <b>had been found sitting</b> in a street corner somewhere in Hanoi, so she took him home.</i><br/><br/>It was not Cathy but someone else who had found her son. Should I rewrite the sentence instead as follows? <br/><br/><i>Cathy said someone else had found her son sitting in a street corner somewhere in Hanoi, so she took him home. </i>
