THREE sets of Sydney shootings have left police mystified with no apparent links between the attacks. SHOTS were fired into a Greenacre home overnight, following shootings at Bankstown and northwest Ryde hours earlier. The Greenacre shooting at 3.15am on Tuesday followed the 12.50am shots in Bankstown. Chief Inspector Glen Fitzgerald from Bankstown says motives for the shootings are a mystery and it's too early to say whether there are bikie links. "Quite frankly at the moment it's got us a little bit baffled," he said. The Ryde location was the same place where a Hells Angel associate was charged for fire bombing a car earlier this year. Two men were seen running from the house late on Monday night in what police believe was a targeted attack. Three men, all related, were inside the home when five shots were fired, including a bullet that hit the lounge room, police say. A 20-year-old Hells Angel associate was charged with the fire bombing, which destroyed the car and damaged parts of the Ryde home.
