KUALA LUMPUR: Police will use a polygraph machine when taking statements from seven witnesses in its probe into the death of fireman Muhammad Adib Mohd Kassim.
Adib was seriously injured in a riot beside the Sri Maha Mariamman Temple at Subang Jaya on Nov 27 last year. He died 21 days later at the National Heart Institute.
On Sept 29 this year, the coroner’s court established that Adib had died after he was assaulted by two or three unidentified people during the riot.
Bukit Aman Criminal Investigation Department director Huzir Mohamed said the seven – who were identified as the main witnesses – were at the scene of the riot.
“We will use a polygraph to gauge if they are telling the truth or not,” he told reporters, adding that a total of 28 witnesses had had their statements taken.
Huzir went on to say that they were working with the Malaysian Anti-Corruption Commission to operate the polygraph and analyse the video recordings that were featured at the inquest.
A polygraph machine measures and records several physiological indicators such as blood pressure, pulse, respiration, and skin conductivity when a person answers a series of questions.
Huzir also said police would soon record statements from UiTM physics lecturer Amir Rafzi Ab Ghani and United Kingdom-based senior forensic and pathology expert Dr Shahrom Abd Wahid, who had both testified at the inquest.
