A Serbian man, 31, was critically injured last night, apparently after being involved in a fight in Paceville.
The police said the man was found lying in in Elia Zammit Street at around 1am. He did not appear to be injured but was allegedly in pain.
Preliminary investigations showed that he had been involved in a fight with a number of men, thought to be foreigners.
Magistrate Consuelo Scerri Herrera is holding an inquiry into the incident.
