A second teenager has been charged over the death of a young woman in a high-rise dispute in Mebourne's CBD.

A 16-year-old Truganina male was charged on Wednesday with being an accessory to murder and assault over the death of Laa Chol, 19, at the weekend.

He has been remanded to appear at a children’s court at a later date.

A 17-year-old, who cannot be named for legal reasons, was also charged over Ms Chol's death and appeared briefly in a Children’s Court on Tuesday.

The court heard homicide squad detectives have more than 50 hours of CCTV footage to analyse alongside mobile phone content.

They also revealed a “large number or witnesses” needed to be processed.

Supported in court by his mother and two brothers, the accused sat silent in the dock during the brief appearance.

Ms Chol, from Pakenham, died following an incident at an out-of-control party at a high-rise apartment in A’Beckett Street during the early hours of Saturday.

The official cause of her 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.

On Monday 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.

Meanwhile, a GoFundMe has been set up by Ms Chol's friends to assist with the costs of her funeral.

The case will return to court in August.
