Three men have been charged with sexually assaulting two teenage girls on the NSW mid-north coast.
NSW Police were called on Saturday night following reports two girls - aged 13 and 15 - had been sexually assaulted by three men at a park in Wingham.
Four men - two aged 21, one aged 24 and one aged 31 - were arrested Tuesday.
The 31-year-old man was released but the others were charged with various sexual assault offences.
Police said all are Tongan nationals and investigators are working with the Department of Home Affairs to determine their visa status.
The three men who were charged were refused bail to appear at Taree Local Court on Wednesday.
