Initially, two suspects were assumed, but research so far points possibly in the direction of multiple suspects.

Two people were involved in the conflict. One of these individuals was injured in the head.

The police have initiated tactical and forensic investigations, are conducting neighborhood inquiries, and are asking witnesses to come forward. It is possible that there were people who saw or heard something during the incident that could help in the investigation. Perhaps someone has information about the person with the head wound. Information can be provided via 0900-8844 or anonymously via 0800-7000.
People in possession of camera footage are also requested to share it.
