KUALA LUMPUR: The naked body of a Chinese national was found, with both wrists slashed, at a service apartment in the city centre.

The woman identified as Kiang Wei, 33, believed to have been repeatedly raped, was found sprawled in a bedroom in a pool of blood at the apartment in Jalan Pasar in Pudu.

At 1.30am on Sunday, an apartment security guard on his rounds found the front door of Kiang's unit, located on the fifth floor, ajar.

Suspecting something amiss, he went inside to check, discovered the body and immediately called the police.

Dang Wangi police chief Asst Comm Zulkarnain Abdul Rahman said a police forensics team inspected the unit and found a bloodstained knife believed to been used in the incident.

"A used condom was found on the floor, near the bed where Kiang Wei was. We believe the victim knew her assailants as there were no signs of forced entry.

"The unit was not ransacked but we still have to verify if any valuables were stolen," he said, adding that police had classified the case as murder.

ACP Zulkarnain said police had yet to establish the full identity of the victim as they only found a photocopy version of her passport.

"We only know that she has been here for several months and we are still checking on her background," he said, adding the body was sent to Kuala Lumpur Hospital for a post mortem.
