Arau police chief Ahmad Mohsin Rodi said the forensic pathologist had concluded that the rupture occurred due to a fall in the restroom, as previously reported, Bernama reported.

“The pathologist also noted that while the fall could have contributed to the rupture, injury patterns on the body do not suggest any signs of abuse.

“Further examination is required to determine the exact nature of the tumour. Samples of the tumour and the detainee’s DNA have been sent to the Penang chemistry department for toxicology analysis,” he said.

Yesterday, it was reported that the 23-year-old man, who had been detained at the centre since Dec 17 for drug abuse, was being treated at the intensive care unit of Tuanku Fauziah Hospital before he succumbed to his injuries.

The initial medical examination found the victim, who is from Langkawi, had suffered internal injuries, specifically to the liver and part of the intestines.

Further medical examination found over a litre of blood in the detainee’s abdominal cavity due to liver bleeding.

Mohsin said the post-mortem conducted at Sultanah Bahiyah Hospital in Alor Setar, Kedah, also found minor injuries, including a forehead laceration, scrapes on the left abdomen and a bruise on the left knee.

The pathologist confirmed these injuries were superficial and non-fatal.

The case has been classified as sudden death pending chemical analysis results.
