Help needed to find missing man Tuyen Duc

The 27-year-old was last seen wearing a blue jumper, blue jeans, black cap and white runners.

Police and family hold serious concerns for his welfare as his disappearance is out of character and fear he could be vulnerable due to his high-functioning autism.

An image of Tuyen Duc has been released in the hope it will assist in locating him.

He may be in the Melbourne central business district, Bendigo or Shepparton areas.

Anyone who sights him is urged to call Reservoir police station on 9460 6744.
