Three men were stabbed in a brawl which broke out in central Birmingham early this morning.
The fight, which erupted around 3am, involved up to a dozen men, with three left with serious injuries.
It happened on Hagley Road, close to a Spearmint Rhino bar and strip club, Birmingham Live reports.
The injured men were said to have transported themselves to hospital, with two presenting themselves at the Queen Elizabeth Hospital with stab injuries.
