He punched his wife in the face twice and left her writhing in pain with multiple fractures in her jaw.
Terrified, she wanted to escape. But he stopped her.
She managed to do so only after she lied that she needed to see a dentist.
Yesterday, Philippine national Ronnie Ambion Vasquez, 26, appeared in court and admitted to one count of voluntarily causing grievous hurt to his wife, Mrs Milagros Castillo Vasquez, 42.
He was sentenced to four months' jail - but not before breaking down in the dock as he pleaded for leniency.
Court papers said that Vasquez, his wife and their daughters were on holiday in Singapore in October when the incident occurred.
FIGHT IN HOTEL
The couple were in their Concorde Hotel room when they got into an argument around 1.30pm on Oct 3. It is unclear what they were arguing about.
During the argument, an angry Vasquez punched his wife twice on the right side of her face.
It left Mrs Vasquez bleeding from the mouth, with the right side of her jaw disfigured.
The assault took place in front of the couple's daughters, who began crying.
It was not clear how many children they have or how old the girls are.
Mrs Vasquez, who became fearful for her daughters' safety, wanted to leave the hotel room but was stopped by her husband.
She then lied to him that she wanted to get her teeth fixed by a dentist.
This sparked another argument but Mrs Vasquez eventually left the room with her daughters.
She immediately went to the hotel concierge and informed the staff about the assault, before taking a taxi to Mount Elizabeth Hospital.
The hotel's security staff checked the room, which was vacant, and found bloodstains on the bed and in the toilet's washbasin.
Hotel staff then went to the hospital to look for Mrs Vasquez, who reported her husband to the police the same day.
Court papers said she was advised to undergo surgery for her injuries.
Yesterday, Vasquez, who has been in remand here since October, told the court that his wife and daughters had flown back to Australia, where they live.
He was unrepresented.
He works in the Philippines and said they had decided to meet in Singapore for a holiday.
He also broke down while handcuffed in the dock.
"I plead for leniency because my wife needs my help," he said.
"I don't want my family to get broken. I won't do this to my wife any more."
District Judge Janet Wang said the court takes a serious view of domestic violence.
For voluntarily causing grievous hurt, Vasquez could have been jailed up to 10 years, caned or fined.
