Victorian Police Interview Partygoers After Teen Death

The 19-year-old victim has been identified as Laa Chol.

Police are interviewing a dozen partygoers and combing through evidence after a young woman died of her injuries after a fight at a Melbourne CBD apartment.

Laa Chol, 19, of Packenham, died during an out-of-control party in the short-term stay unit on the 56th floor of the EQ Tower early on Saturday morning.

A group of young African Australians, aged in their late teens and early 20s according to media reports, had rented the apartment for the party when a second group arrived and a fight broke out.

Police were not forthcoming with details, saying Ms Chol had been "assaulted" when asked about the cause of her death.

Friends, family and members of the African-Australian community have paid tribute to Chol on Facebook, saying she was "a beautiful soul".

The second group cleared out before police arrived, but detectives are hoping CCTV footage will help them identify the killer or killers quickly.

Officers were called to the scene of the teen's death -- an address on A’Beckett Street -- following reports of a woman suffering serious injuries. Paramedics attended but the victim died at the scene.

North West Metro Police Commander Tim Hansen told media on Saturday afternoon the victim, from Pakenham, was a short term renter on the 56th floor of the EQ Tower.

“My understanding is this wasn’t a random attack,” Mr Hansen told media.

“There’s no sign of forced entry but we’re trying to clarify what brought [the second group] there.

“Police arrived to what was a fairly chaotic scene.”

He said the only known link between the two groups at the party was that they were both of African-Australian heritage, aged about 19-20 years old.

Several people are currently being interviewed by the Homicide squad.
