A pregnant woman waiting for a taxi in Dunearn Road in April last year was jabbed in the abdomen by a stranger.
The victim, 29, who was then seven months pregnant, suffered pain and had to be taken to hospital. She recovered and had a normal delivery.
Yesterday, the attacker, Lee Su Min, now 53, was sentenced to undergo one year of mandatory treatment.
The unemployed woman pleaded guilty to hurting the victim and also slapping a 36-year-old cashier with a book at the Popular Bookstore in Bras Basah Complex in October 2011.
A district court heard that Lee suffers from bipolar disorder and had not taken her medicine when she committed the offences.
Defence counsel Jeanny Ng argued for a mandatory treatment order for her client.
The lawyer said that Lee had a 19-year-old daughter from a previous marriage.
She previously suffered from post-natal depression and had to be admitted to Mount Elizabeth Hospital for three weeks.
The couple divorced in 2001 and this brought about a relapse of her depression.
Lee also slapped three other women in 2010 and 2011 and stole items worth a total of $36 from the Cold Storage supermarket in Bukit Timah Road.
These charges were taken into consideration by the judge when passing sentence.
For causing hurt to her victims, she could have been jailed for up to two years and fined up to $5,000.
