Man dies in bike crash at Port Melbourne

Dashcam footage is being sought of a fatal motorbike accident in Port Melbourne in which a 32-year-old man died.

It's believed the Highett man lost control around a bend as he took the exit ramp towards the Burnley Tunnel and was thrown over the ramp after crashing into a side barrier about 10pm on Sunday.

He died at the scene, with police wanting to speak to the rider of a second motorbike observed riding alongside at the time, with witnesses reporting the two bikes may have been racing.
