A post-mortem on a 42-year-old man who died after being detained by Cheras police found external injuries on his body. Bukit Aman disclosed the finding but stopped short of giving a cause of death. Investigators are waiting on laboratory results before a final conclusion is issued. The case has put the spotlight on how the man was treated during his time in custody. Police say the standard procedures that follow a death in detention are being observed. The lab analysis is expected to clarify whether the injuries were linked to the death itself. Until those results are in, authorities say no conclusions should be drawn. Whatever the findings show will shape the action that follows.
