A 31-year-old man has been arrested as part of an investigation into the death of 21-year-old Jayda Lou-Eve Allen Bonner.

Victoria Police say the man, who turned himself in following the death of the Yagera woman in a Melbourne apartment over the weekend, knew the deceased.

Jayda was found deceased at a residence on Cardigan Street in the inner-north suburb of Carlton at about 1.45 am on Saturday.

"The Carlton man handed himself into a police station and is now expected to be interviewed by Homicide Squad detectives," Victoria Police said in a statement.

"Investigators believe the parties were known to one another.

"A 60-year-old man was arrested shortly after the incident and released pending further enquiries."

There has been an outpouring of grief following the 21-year-old's death, with a smoking ceremony planned at the Lygon Street housing towers over the weekend.

It is understood Jayda's family had been so concerned about her safety that they sought police intervention six weeks before her death. However, the request was later withdrawn.

"The really horrible, horrible thing is that the system's so broken that about six weeks ago, we begged for their help," her aunt, Kellie Carter-Bell, told the ABC over the weekend.

"We begged for their help, and because we were ringing them and not Jayda, their attitude was, 'Well, what do you want us to do?'"

Following the man's arrest on Tuesday, Ms Carter-Bell told The Age that the alleged abuse Jayda suffered in her final weeks, and the nature of her injuries, meant the family was unable to see her body to say goodbye.

However, her mother was able to hold her hand one last time.
