Police and paramedics were called to a convenience store on Redfern Street about 11.30pm, where a fight had broken out between the five men.

Paramedics treated one man, aged 26, for facial lacerations, and he was later taken to St Vincent's Hospital.

Another man, aged 24, suffered injuries to his ribs and a third, aged 31, was treated at the scene for the effects of pepper spray. Both were taken to Royal Prince Alfred Hospital.

The remaining two men, aged 21 and 26, were arrested near the store, but have been released without charge while inquiries continue.

"We're still trying to find out why the brawl broke out and the appeal for public information remains pertinent," a spokeswoman for NSW police said.

Police have not released details about the store, with the spokeswoman saying: "The store is just as much a victim of crime."
