A homicide investigation is under way after a man was injured and found unresponsive in a Western Australia car park.
Authorities responded to an incident call at Kwinana Beach about 6.10pm on Thursday, where a 56-year-old man was found unresponsive.
Attempts to revive him were unsuccessful and he died at the scene.
Police believe the man may have been involved in an altercation, with a another man - also in his 50s and allegedly known to the victim - assisting with inquiries.
Detectives are appealing for anyone with mobile or dash cam footage to come forward.
