Senior Sergeant Steve Pivac said the arrests came after a serious assault in Stanmore Bay on January 4.
"A group of males approached another group outside the Brightside Rd shops," he told the Herald.
"An 18-year-old male victim was assaulted by one of the alleged offenders and knocked to the ground.
"A second victim, a 20-year-old male, was seriously assaulted by the group of males, sustaining multiple injuries including a fractured jaw."
Pivac said since the assaults police have carried out a number of inquiries.
This morning they executed search warrants at three addresses.
As a result, the five teens were arrested and charged.
It is understood the alleged offenders are part of a youth gang based in the area.
It is believed that the gang may be responsible for numerous other serious assaults.
"They are basically going around and beating the sh*t out of people," said a source.
"They are very serious assaults."
Police urged anyone who had been targeted or had seen anything to come forward.
"This was a serious incident and police and the community will not tolerate this type of violent behaviour," he said.
"We want our community to feel safe.
"If anyone has witnessed any incidents of a similar nature, we urge them to contact their local Police station to report the matter and we will investigate any complaints thoroughly."
Inquiries are ongoing into the incident and police are unable to rule out the possibility of further charges.
