POLICE cordoned off a construction site in Clementi on Thursday and took blood samples from about 200 foreign workers hours after a woman was sexually assaulted in a nearby park.
The victim, believed to be a National University of Singapore student in her mid-20s, was attacked on Wednesday night at around 10.40pm.
It is believed that she was set upon while walking on a footpath through the Clementi Woods Park, which is just opposite the university.
While the police would not comment on the nature of the offence, The Straits Times understands that the Special Operations Command (SOC) was activated.
The unit is used to maintain public and during tactical operations, among other things.
