Five shootings within a few hours - and a machine gun spraying bullets in a suburban street - as a war between rival bikie gangs ramped up to terrifying heights. Senior police conceded it was a "shocking" few hours, with the first gun fired at a Granville house just after midnight yesterday. Gunfire continued throughout Sydney's western suburbs four more times before dawn. Senior police tried to deny a full-blown bikie war was imminent while at the same time admitting a turf war between the Hells Angels and Nomads outlaw motorcycle gang members were behind four of the five shootings. A fifth shooting at Northmead was not bikie linked, instead believed to be the result of business dealings gone bad.
