A second teenager has been charged over the death of 19-year-old Laa Chol at a party in a Melbourne CBD apartment.
A boy, 16, was charged on Wednesday with being an accessory to murder and assault, two days after police charged a 17-year-old Sunshine North boy with Ms Chol's murder.
The 16-year-old from the western suburb of Truganina is in police custody and will appear at the children's court at an undisclosed date.
Laa Chol died after she was assaulted at a party she attended on the 56th floor of the EQ Tower in Melbourne in the early hours of Saturday.

Police allege she was attacked amid a dispute involving two groups of party-goers, including one that hired the short-term stay apartment and another that arrived later.
Commander Stuart Bateson told 3AW on Monday the young woman's death had nothing to do with Sudanese gang violence, as had been suggested by some politicians.
"When we start to make an issue that is bigger than what it is and when we start to racialise and we start to target this specific community, that leads to some unintended consequences," he said.
