GEORGE TOWN (BERNAMA) - The urine and blood samples of two more victims who experienced fatigue and dizziness after drinking premixed coffee were found positive for syabu.

Penang police chief Datuk A.Thaiveegan said the results were obtained last week but the police were still waiting for the chemistry department to produce results of the coffee samples.

He said so far, test results of blood and urine samples of four individuals, including the two men who drank the durian-flavoured instant coffee, were tested positive for methamphetamines.

"Police are still investigating whether the coffee had been mixed with drugs by certain syndicates but to date, we have not come to any conclusion on involvement of syndicates, because we have yet to make any arrest.

On Feb 4, two men were admitted to Penang Hospital (HPP) after drinking the premixed coffee, which left them dizzy and nauseous.

Earlier, five individuals, which included two women, were treated at the same hospital when they experienced extreme fatigue after allegedly drinking a "durian white coffee" mixture.

The seven people, aged between 19 and 62, were warded for observation and tests on two of the seven individuals were found positive for syabu.
