Police have charged a 17-year-old male with murder after a young woman was killed following a high-rise dispute.

The teenager from Sunshine North was taken into custody on Monday afternoon following the fatal assault in Melbourne's CBD in the early hours of Saturday morning.

A 17-year-old boy is due to face the children's court today over the death of 19-year-old Laa Chol.

He was questioned by homicide squad detectives and has since been charged with one count of murder.

He was remanded and will appear at a children's court on Tuesday.

Laa Chol, 19, was killed during an out-of-control party at a short-term stay unit on the 56th floor of the EQ Tower early on Saturday morning.

Ms Chol, from Pakenham, died after a fight between the group that had hired the apartment and another group that arrived later.

The official cause of death has not been confirmed by police, but it is understood the young woman was stabbed during a fight that broke out in the apartment.

The arrest came on the same day as the head of Victoria Police's priority communities division said there was no indication the young student's death had anything to do with "warring factions" in the South Sudanese community.

"The suggestion Laa Chol was a member of a gang is just not true. That's not the information we are getting from the community or her family," Commander Stuart Bateson said.

Police said on Sunday they did not believe the second group was invited to the gathering by either the person who booked the apartment, or the deceased, Ms Chol.

Ms Chol was a second-year legal studies student and talented soccer player who has been remembered by friends on social media as a “positive and bright young lady”.

She was remembered by her soccer club Skye United FC as a "very skilful and hardworking winger who was an integral part of the senior women’s team".

At a match on Sunday night, a minute's silence was held to remember Ms Chol, as well as a player from the opposing Monbulk Rangers Soccer Club who had passed away from cancer four years ago.

Both teams also wore black arm bands to remember the women.

Community members who are attending a protest on Saturday afternoon have suggested wearing blue to remember Ms Chol.

Police declined to comment further.
