Two men were hurt, one of them seriously, after a fight broke out in Buġibba at 10.30pm last night.
The police said that the man, a 37-year-old Libyan from St Paul's Bay, tried to stop a group of people, who were most likely foreign nationals, from assaulting two people who were sitting next to him.
Things seem to have escalated and the man was hit over the head with a glass.
Another man, a 25-year-old Libyan from Gżira, was also slightly hurt during the altercation.
