The 14-year-old First Nations girl at the centre of an alleged assault in Cairns has provided an update on her condition after being taken to hospital earlier this week.

She confirmed she sustained bruising to her body and soreness to her head but has since been cleared by doctors.

She said she is now recovering and intends to press charges against the men involved.

"I should be okay… I'm also pressing charges against them," she said in a message.

The girl's family said she was still shaken by the incident and remains traumatised after being attacked.

They described her as scared to walk anywhere and confirmed she has made a formal statement to police.

Queensland Police Service earlier confirmed detectives from the Child Protection Investigation Unit are investigating and have obtained the identities of all involved.

Police said they are canvassing CCTV and appealing for further witnesses.

The incident gained national attention after footage circulated showing three men standing over the girl as police placed her in handcuffs.

One of the men was later dismissed from his place of work after community outcry over his social media posts linked to the case.
