The body of a young woman was found in a Circuit Road flat on Tuesday night (March 22), local media reported.
Chinese evening daily Lianhe Wanbao reported that the landlord made the grisly discovery in the locked room of a male tenant who recently left the country.
He had returned to the flat to check on the vacated room after his tenant told him he was going on a work trip in Malaysia for some time.
Shin Min Daily News reported that the landlord entered the room using a spare key and thought his tenant was sleeping when he first saw someone covered with a blanket in bed.
After he returned to the room later that night, he realised that the body was motionless and made a police report.
The deceased woman, a 28-year-old Chinese national, was pronounced dead at the scene by paramedics. She did not have any visible injuries, Wanbao reported.
According to Wanbao, other tenants identified the deceased as the male tenant's girlfriend who would visit and stay over at the flat occasionally.
The man is currently uncontactable.
The police has classified the case as an unnatural death. Investigations are on-going.
