Boy missing from Kingston, Logan in Queensland with police holding grave concerns

Grave fears are being held for a seven-year-old boy who has disappeared in Queensland.

The boy, who has a medical condition and is non-verbal, was last seen at a home on Queens Road in Kingston, Logan, at about 5pm on Saturday.

Police say the boy may be at 'significant risk' and are concerned for his welfare due to his young age and medical history.

A police helicopter has been called in to help scour the area for the child.

Residents have been asked to check their homes and any structures including sheds in case the seven-year-old is hiding. 

The boy is described as being Polynesian in appearance, with shoulder-length, dark wavy hair.

He was last seen wearing a blue shirt and underwear.

Anyone with information is urged to contact police.
