Homicide detectives are investigating the fatal stabbing of a teenager in Melbourne's bayside suburb of St Kilda on Sunday night.
Police were called to St Kilda beach just after 7:30pm following reports a group of people were fighting.
Hashim Mohamed, an 18-year-old from Tarneit in Melbourne's outer west, was found with stab wounds on the beach near Pier Road.
He was taken to hospital, where he died.
Acting Inspector Nigel L'Estrange said a group of up to six people was believed to have been involved in the incident.
"We believe we will identify these people. There were a number of CCTV cameras in the area," he said.
"We will be hopefully making arrests soon and we will bring these people to justice."
Acting Inspector L'Estrange said the knife used to kill the man had been recovered but it was believed some of the other people involved were also armed.
"There's a number of youths out there carrying knives and these are the consequences that come from this and they're lifelong," he said.
"There's a family now that will be going into Christmas with the loss of a loved one."
Police said it was believed the people involved were young males of African appearance.
Local resident Jonathan was walking his dog near the popular foreshore when he saw a group of men fighting at the beach.
He said the incident was likely to have been witnessed by multiple people who were in the area at the time.
"It was packed, I walked along and thought this is like Bondi," he said.
"Everyone walking, everyone partying and picnicking on the beach."
Acting Inspector L'Estrange said he wanted to assure people Melbourne was a safe place.
"We do have a number of extra police out at beach locations and holiday spots over the summer," he said.
Police said there was nothing at this stage to suggest the fight was gang related but they urged anyone with information or footage to contact CrimeStoppers on 1800 333 000.
