Athens - An Australian tourist remained in a coma in a Greek hospital on Wednesday following an alleged beating by four nightclub bouncers on the popular Cycladic island of Mykonos, according to reports.

The 20-year-old man was in the company of five other Australians when they became involved in an argument with the bouncers, reports said.

The man was reported to have been struck on the head with an iron bar during the fracas. Two others suffered minor injuries.

Four people are scheduled to appear before a public prosecutor on Thursday. (dpa)
