Queensland Police have charged four men in an ongoing investigation into the alleged rape of two teenage girls in a southern Brisbane suburb.
Police say two 15-year-old girls met with a group of men at a park in Calamvale last December.
Authorities understand the girls were repeatedly sexually assaulted at the park.
The men charged, aged between 19 and 22, face 40 offences each.
The charges include rape, indecent treatment of a child under 16, stupefying to commit indictable offence, taking a child for immoral purposes and assault with intent to commit rape.
Two men appeared in the Brisbane Magistrates Court on Saturday.
A further two men will appear in the Richlands Magistrates Court on February 1.
Investigations are continuing under the Inala Child Protection Investigation Unit.
