Man planning to rape flatmate wrongly spiked her drink with erectile dysfunctional pills bought from Geylang

A 28-year-old man was sentenced to two years and 10 months' jail with three strokes of the cane today (June 6), for spiking his flatmate's drink in an attempt to rape her.

Indian national Annadurai Prabakaran had added what he thought was a sleeping pill into the victim's drink, reported The Straits Times.

But the 21-year-old woman spat out the contaminated liquid upon tasting its bitterness.

The private hire bus driver pleaded guilty to one count each of administering a drug to the victim and obstructing the course of justice.

Annadurai has worked in Singapore for over seven years, and lived in a Tampines flat with the woman - who is an Indian national as well - and her uncle's family.

Deputy Public Prosecutor Rachel Tan said that he had been harbouring fantasies about the woman but did not think that she would have consensual sex with him as the two had never spoken to each other.

He then planned to drug the woman with the two pills he bought from Geylang on Dec 9 last year, before raping her while she slept.

The court heard that the pills contained sildenafil, which is an active ingredient in Viagra, a drug used to treat erectile dysfunction.

Three days after buying the pills, Annadurai spiked the woman's unattended bottle of water when the two were alone at home, as the rest of the occupants were in India.

He waited in his room after adding one pill into the bottle. The woman, however, spat out the drink upon realising something was wrong.

Out of fright, she called her uncle's friend and cried as she told the latter what happened. 

The 36-year-old friend soon arrived with a 41-year-old man, and noticed how cloudy the victim's drinking water looked.

Annadurai then admitted to adding a pill into the bottle and begged for forgiveness after being confronted.

But he suddenly seized the bottle and tried emptying its contents while the victim and her two guests stood at the corridor in front of the flat.

However, the bottle still contained some water after Annadurai dropped it on the floor. The older man then alerted the police after picking the bottle up.

An analysis by the Health Sciences Authority revealed that there was sildenafil present in the water.

Annadurai's lawyer, Mr Kalaithasan Karuppaya, pleaded for his client to be given the minimum sentence possible.

He also added that the Indian national was remorseful and had acted out of character.
