Man punched 9 yo in face at Qld playground

Police in Brisbane are hunting for a man who allegedly punched a boy in the face before throwing him to the ground and trying to strangle him in a playground last month.

The nine-year-old was playing with other children at a park in Algester on the afternoon of September 25 when he was allegedly assaulted by the man before he could run away without sustaining any serious injuries.

Police have released a computer-generated image of a man who may be able to assist them.
