Fears for missing NSW man with disability

The family of a missing man in Sydney's southwest say they are concerned for his welfare because he has intellectual disabilities.

Aakash Kumar went missing on Saturday while he was travelling from Liverpool to the Moss Vale area.

His family, who have appealed to the public, say the 23-year-old has an intellectual disability which causes him to behave younger than his age.

Mr Kumar is described as being of Indian sub-continental appearance, about 190cm tall with a thin build.

He was last seen wearing black pants and carrying a black and orange "Fit n Fast" backpack.
