Sydney drive-by shootings Mother and son have escaped injury

Mother and son have escaped injury during the latest in the spate of Sydney drive-by shootings, police said today.The pair were inside their Sartor Avenue home at Bossley Park in Sydney's west about 10pm (AEDT) last night when the property was showered with gunfire. "Several shots were fired into the home, penetrating the front of the house," police said. "Two occupants - a man and a woman - were at home at the time. However neither were injured in the incident." Investigators are yet to confirm if the incident is related to a similar attack on the same day that sent two men to hospital. At about 1am (AEDT) yesterday afternoon at Auburn, in Sydney's west, seven houses in three streets were sprayed with gunfire. An 18-year-old man was shot in the leg and a 17-year-old male was treated for lacerations and then arrested but later released. Police are investigating if outlaw motorcycle gangs are to blame for the Sunday morning attack.
