Boy assaulted at Sydney convenience store A TEENAGER has been assaulted after going to his mother's aid when she confronted boys she suspected of shoplifting in her western Sydney convenience store. Two teens allegedly attempted to steal items from the Parramatta store around 8.30pm (AEST) on Wednesday, before being confronted by the female store owner. When her 14-year-old son came to assist her, he was assaulted by the two boys, who punched him in the face a number of times, causing facial injuries and knocking out some of his teeth. The pair fled the store but were arrested nearby and will be interviewed by detectives. The victim was treated in Westmead Children's Hospital.
