Man identified as Suresh David Narasimmalu, 29, stabbed his wife Vasentha Kumari, 30, in the abdomen in front of their two sons aged five and seven, during a Diwali shopping at Little India in Singapore on October 18, 2014, reported the Straits Times.
Narasimmalu stabbed his wife in the abdomen after heated argument took place between both of them as they walked along Race Course Road in Little India. Later he took taxi to flee.
Kumari, who was left bleeding, called the police. She spent six days in the hospital. Narasimmalu was arrested several hours later from his brother's home.
The court heard that the couple were in the middle of a divorce.
Deputy Public Prosecutor, Carene Poh, said Narasimmalu's knife attack was "not only vicious but gratuitous".
Narasimmalu's defence lawyer said his client's actions were not premeditated but provoked by his wife who had left him for a boyfriend.
He added that Narasimmalu had been "under enormous stress from the failed marriage, not being able to see his children daily and from the betrayal of the victim".
The defence lawyer explained that Narasimmalu was carrying the knife as a work tool.
For voluntarily causing hurt with dangerous means, Narasimmalu can be jailed for up to seven years, fined and caned.
