Mapp said police have been carrying out numerous inquiries into the assault, including identifying footage of a man in the area at the time.
Anyone who knows who the man is should contact police.
The man was wearing black clothing and black shoes, all Nike-branded. The man’s hoodie and track pants had Nike branding in a gold or yellow colour.
“Violence like this has no place in our community and I’m asking the public to assist our investigation so this man can be held accountable,” Detective Sergeant Mapp said.
“There will be people in the community that will know who this man is and recognise the outfit he’s wearing.
“They need to do the right thing and contact Police so we can speak with him.”
