Detectives allege an altercation broke out on the footpath, during which a 21-year-old man was stabbed multiple times in the chest.

Two men allegedly fled the scene on foot and were arrested nearby on Costin St.

The French tourist was out with his friends when he saw a fight breaking out outside a bottle shop, and he tried to intervene.

“We had a friend that was trying to ... break up a fight,” the man’s friend Hugo told 7NEWS.

“Two people were fighting, and he was right in the middle and he got stabbed, I think, three times and he started bleeding a lot.

“And then we called the ambulance and the police and they arrived pretty fast.”

He was rushed to hospital in a serious but stable condition.

An 18-year-old Zillmere man has been charged with one count each of acts intended to cause grievous bodily harms, assault, and carrying a knife in public.

An 18-year-old Bald Hills man faces one count of acts intended to cause grievous bodily harm.

Both are due to appear before Brisbane Magistrates Court on July 26.

Queensland Police said investigations into the circumstances of the incident are continuing and urged witnesses to come forward.
