Police are appealing for public assistance to help locate a missing 13-year-old Research boy.
Police say the teenager, named Tom, was last seen in Research about 6pm yesterday.
Tom is described as 160cm (5ft2) tall with a medium build and short dark blond hair.
Police and family have concerns for his welfare as he has autism.
“He may be in the Greensborough or Melbourne CBD areas and will most likely have his black mountain bike,” Victoria Police said in a statement.
Police have released an image of Tom in the hope someone can provide information on his current whereabouts.
Anyone who sees Tom is urged to contact Eltham Police Station 9430 4500.
