The Shah Alam police centralised lock-up sentry supervisor said he saw custodial death victim S Balamurugan trembling badly when he received the detainees at the lockup.

Cpl Muszanizam Mustaffa said he was told by Balamurugan's "case mate" that the trembling man had an "alcohol addiction" (ketagihan arak), and that he believed the man because he could smell alcohol.

However, Bar Council's R Sivaraj pointed out that the two men arrested with Balamurugan, K Tamilasan and a juvenile with the surname Ang, could not speak Malay.

"I suggest you are not telling the truth, because they cannot speak in Malay.

"They had to use a translator (when they gave their testimonies)," Sivaraj said to Muszanizam during the Enforcement Agencies Integrity Commission (EAIC) public inquiry into Balamurugan's death in Putrajaya today.

The police officer then said he was not sure if it was either Tamilarasan or Ang who said that as they were brought to the Shah Alam lock-up in a group of six detainees.

Six detainees, from two separate cases, had been brought to the Shah Alam centralised lock-up from the North Klang district police station around 3.30am on Feb 7, he explained.

Human Rights Commission of Malaysia (Suhakam) representative Sarah Adibah Hamzah then pointed out to Muszanizam that he had said to Suhakam on Feb 15 that it was one of the police escorts who told him Balamurugan had an "alcohol addiction" (ketagihan arak).

Muszanizam said it was both the police escort and one of the detainees who told him about Balamurugan's supposed alcohol addiction.

EAIC chairperson Yaacob Md Sam had also asked Muszanizam on the possible causes for someone trembling badly.

"Scared, fever, feeling unwell," the police officer listed out.

"(But in Balamurugan's case) it seemed like it was (due to the withdrawals from) addiction," he added.

He also said that apart from the trembling, he did not see any other signs of injury on Balamurugan.

"I didn't see any blood on Balamurugan. He could change clothes on his own without any help," he said.

Muszanizam was the 34th witness to be called, out of the 55 expected witnesses.

Cpl Ridhwan Mohammad and L Cpl Mohd Taufik Awang, the 30th and 31st witnesses respectively, had escorted Balamurugan and fellow detainee K Tamilarasan from the Bandar Baru Klang police station to the North Klang station around 11.45pm on Feb 6.

Both the police officers said they did not smell any alcohol on the two detainees whom they were escorting.

Det Cpl Mohd Reduwan Musa and one other police officer then escorted Balamurugan and Tamilarasan from the North Klang station to the Shah Alam lock-up a few hours later at 3.30am on Feb 7.

Reduwan told the inquiry that there was a strong alcohol smell from the two detainees then.

Later that morning of Feb 7, Balamurugan's remand application was rejected by the Klang magistrate court, and he was taken back to the North Klang police station. He was found dead in the police station in the early hours of Feb 8.

Coroner Ahmad Azhari Abdul Hamid said he received a call about the death of a detainee around 3.40am on Feb 8 and arrived at the police station around 5am.

He said he examined the body and found no injuries or blood from Balamurugan's neck downwards, but there was blood from the deceased's mouth and nose.

After his examination, he said he told the police officers to bring the body to the hospital for a post-mortem.

Today marks the last day of the second series of the hearing on Balamurugan's death.

The next series of hearing will resume on July 10.
