An 18-year-old man has become the sixth teenager charged following the fatal stabbing of Hashim Mohamed in an inner Melbourne beachside suburb.
The Tarneit man, also 18, was discovered with stab wounds near St Kilda beach on December 4 and later died in hospital.
On Friday, an 18-year-old from Albion was arrested at a bus stop in Deer Park, in the city's west, by police from the Gang Crime Squad.
He was charged with violent disorder and affray.
Five other males, aged between 15 and 17, were previously charged with various offences as part of the investigation.
The probe is ongoing and anyone with information about the incident has been urged to come forward.
