Police and emergency services responded to reports of a single motorbike crash in Niddrie last night.
Investigators attempted to intercept a motorbike on the Tullamarine Freeway near Bulla Road about 9.15pm.
The rider failed to pullover and police did not pursue the motorbike.
About 5 minutes later, police received reports that a motorbike had crashed on the Calder Freeway near the Milleara Road off ramp.

The exact cause of the crash is yet to be determined and the investigation remains ongoing.
