A Hanoi woman who spent two nights at the Vissai Hotel in Ho Chi Minh City last week claims she awoke on Sunday to find her three-carat diamond had been pried from the ring on her finger.
A receptionist at the Vissai Hotel declined to comment on the issue and said her manager was out when Thanh Nien News called on Tuesday.
The Hanoi woman, whose name was given only as D.T.H.N, notified police soon after discovering that the biggest diamond on the ring she wore on her right middle finger the night before, had disappeared.
The rest of the ring had been left untouched, but she found a small graze on her finger near the ring, N. told police.
The 38-year old woman said she traveled to Ho Chi Minh City on Friday (November 7) and rented a room at the Vissai Hotel on Nguyen Van Troi Street in Phu Nhuan District.
N. told police that a relative gave her the diamond ring and estimated its worth at nearly US$100,000 (over VND2 billion).
The woman said she worked in her room until midnight on Saturday and recalled drinking from a half-empty water bottle before going to bed.
She claims she drank most of the water early that day and left it in her room before heading out at 4 p.m.
N. said she did not return to the hotel until 10 p.m. that night and went to work before losing consciousness around midnight.
“I think someone drugged my unfinished water to knock me out,” N. told Thanh Nien News.
“I'm a light sleeper. I should heard if someone broke into my room and pried the diamond out of the ring. However, I was sleeping like a rock that night.
“When I woke up, I felt totally exhausted.”
N. said she has since been hospitalized due to the alleged affects of the drug.
Phu Nhuan District police say they are investigating the case.
