A 31-year-old Sri Lankan, Amesha Rajapakse was found dead in a Western Sydney creek at Westmead on Tuesday.
Sahan Rajapakse, the brother of Amesha Rajapakse, said his sister had gone out to buy food around 7.30pm but never returned.
She was reportedly found with a scarf around her neck in a swollen creek in a hard-to-get to area on the other side of a large wall.
Amesha arrived from Sri Lanka in 2009 and was an IT graduate.
Police were awaiting a post-mortem report to determine if Amesha’s death was suspicious.
