ABOUT THE CASE
Azuar Ahamad has pleaded guilty to raping four women in 2009 but he is now on trial for allegedly drugging his victims.
He got to know the women through the Speed Date application on Facebook and met them for drinks at pubs.
All four victims reported blacking out after consuming a drink he bought them, and they could not remember anything until they came to the next morning.
It was revealed that Azuar had raped or sexually violated the women and recorded the crimes on his phone.
He pleaded guilty to rape in August 2012 but denies drugging the women with sedatives.
Instead, he says they drank themselves into a stupor.
There is now a trial-within-a-trial, or a Newton hearing, in which the prosecution is trying to prove that Azuar had spiked the women's drinks.
