Detectives investigating the fatal stabbing of a 17-year-old boy at a party south of Perth have made further arrests, with five young men now charged with his murder.
Chikayne-Nadante Heslip died in Rockingham Hospital after being stabbed outside the house party in Waikiki on Saturday night.
Police allege Mr Heslip had come to the aid of his friends before being chased from the party and attacked by a group of gatecrashers at two different locations.
A 17-year-old boy and two men, aged 18 and 27, were initially charged with his murder. They were refused bail and faced court on Thursday.
Homicide detectives have since charged another two men, aged 18 and 19, with murder.
They have been refused bail and will face Rockingham Magistrates Court on Friday.
In a statement, Mr Heslip's family said their "beautiful, caring young man" had always put others first.
"Our understanding is that Chikayne died protecting his mates and in our eyes, he will always be a selfless hero," the family said.
"You will always be remembered as our hero."
WA Police Assistant Commissioner Brad Royce said a family sending their 17-year-old to a party should not have to face such a devastating outcome.
"The people responsible for this were cowards. There was a number of them and one boy," he told reporters.
Mr Royce said it was becoming common for house parties advertised on social media to become out of control and attract violence.
"Once you're on social media the party expands, the numbers expand," he said.
"The people managing the party aren't always prepared for those numbers and have to shut things down. And a lot of the trouble occurs outside the party."
