POLICE are hunting a man with a shaved head and tattoos on his neck and arm after a female cyclist was left for dead in a hit-run in Toolern Vale, in Melbourne’s northwest.

The cyclist suffered critical injuries after being struck by a white Holden Commodore about 12.45pm on the Gisborne-Melton Rd.

Police are looking for the driver, believed to be a Caucasian man in his early to mid 20s, who failed to stop after the incident and may still be in the Toolern Vale or Melton areas.

The white Commodore is a VT or VX sedan and will have visible damage to the front passenger windscreen, front guard and side mirror.

Local police have saturated the area hunting for the man and Major Collision Investigation Unit detectives are investigating.

Police urged anyone who may have information to call 000 immediately.
