Seven teenagers have been charged with murder following the death of a 27-year-old man who was allegedly assaulted in Brisbane's Kelvin Grove area last month.

Police allege the man was attacked before his vehicle was stolen. He was taken to hospital with serious injuries and later died.

The teenagers, aged between 14 and 17, are facing murder charges in connection with the man's death. The case has now progressed through the Queensland court system, where the allegations will be tested through the legal process.

The incident has attracted significant attention because of the ages of those charged and the circumstances surrounding the alleged attack. Police have continued investigating the events leading up to the man's death and the circumstances surrounding the vehicle theft.

The charges follow an earlier investigation into the alleged assault in Kelvin Grove. Investigators have been working to establish the roles of the teenagers and the sequence of events before and after the incident.

The accused teenagers appeared in court and were kept behind bars while the legal proceedings continue. Further hearings are expected as the prosecution and defence prepare their respective cases.

Because the matter is before the courts, the allegations against each teenager remain unproven. All accused people are presumed innocent unless found guilty by a court.

The case is another significant development in Brisbane's criminal justice system and is expected to remain before the courts as investigators and prosecutors continue preparing the matter.
