Lawyers representing the family of the death-in-custody victim D Vickraman, 37, has called for an immediate inquest on his death.

They said a post-mortem had found that Vickraman had died of non-compaction cardiomyopathy - a birth defect afflicting the heart - which raises questions about the circumstances surrounding his death.

In a joint statement, the two lawyers Eric Paulsen and Melissa Sasidaran said the Vickerman's family had informed them that the deceased was a healthy man with no history of heart disease.
