The married couple were waiting for the hotel lift when they saw a young woman staggering towards them.
She was naked and covered in blood.
When they asked her if she was all right, all she said was: "Can you help me?"
These details emerged during the testimony of hotel guests, Mr Mohamed Firdaus Kamsani and his wife, Madam Farizah Abdul Aziz, in the High Court yesterday.
They were called as prosecution witnesses for the trial of Giselle Shi Jia Wei, 25, who is accused of the attempted murder of her former girlfriend, Miss Ummul Qurratu 'Ain Abdul Rahman, on July 22, 2012.
Shi had allegedly stabbed Miss Ummul twice in the chest with a knife in Room 801 of the Golden Star Hotel in Geylang.
Mr Mohamed Firdaus and his wife had occupied Room 803 and were waiting for the lift at about 5.40pm when they saw Miss Ummul.
She seemed weak and covered in blood. As she was naked, she used her hands to cover her chest and her private parts, Madam Farizah told the court.
All she could make out was Miss Ummul saying: "Can you help me?"
TRIED TO KILL HER
Mr Mohamed Firdaus went back to their room to get a towel while Madam Farizah held on to Miss Ummul.
"She told me someone had tried to kill her," Madam Farizah said.
When her husband came back with the towel, she used it to cover Miss Ummul's chest and helped her into the lift.
Inside, she asked Miss Ummul if her boyfriend was the one who had stabbed her.
Miss Ummul replied that it was her friend, before repeatedly asking the couple to call the police.
In the lobby, Mr Mohamed Firdaus called the police while his wife helped Miss Ummul to a sofa and got another towel to cover the injured woman's lower body.
When Madam Farizah asked if her friend was still in the room, Miss Ummul seemed too weak to answer, but said repeatedly that her belongings were still in the room.
"I told her the police would take care of that. I kept talking to her to keep her awake," Madam Farizah said, adding that Miss Ummul had told them that she found it hard to breathe.
TWO BLEEDING WOUNDS
Also taking the stand yesterday afternoon were the paramedics who went to the scene.
Warrant Officer 2 (WO2) Zohri Anwar said that when he got to the hotel, Miss Ummul was on the sofa and seemed weak. But she could tell him that she had been stabbed.
He noticed that she was still bleeding from two stab wounds on her chest.
