The woman allegedly involved in the fracas at Heng Long Teochew Porridge restaurant last month was remanded in the Institute of Mental Health (IMH) yesterday.
The court heard yesterday that Pang Pei Pei, 40, who is a mother of a five-month-old baby girl, has managed to make arrangements for her daughter's care.
On May 31, her lawyer, Mr K. Ravendra, told District Judge Kan Shuk Weng that his client probably suffers from post-natal depression.
Judge Kan then said that Pang had told the investigation officer that she had gone to IMH for treatment, but had not been following up on it. The judge also said she had not been taking her medication.
Pang was one of three people charged in court last week with performing a rash act at the eatery. The other two are Tan Sung Meng, 46, and Ang Sim Poh, 48.
The trio are accused of throwing bowls, tables and chairs there at around 3.45am on May 27.
Police are still investigating a fourth man, Mr Yeoh Keng Hock, 53.
The ruckus last month allegedly erupted after a group of diners became upset with the $28 bill they received for their meal of porridge, pomfret and several side dishes.
According to a cleaner, the customers threw furniture and other items after arguing with a staff member.
An 80-second video of the incident was later uploaded online and showed at least three people picking up objects such as chairs before flinging them onto a food counter.
Ang and Tan, who are out on bail of $5,000 each, have had their cases adjourned to June 21. Pang will be back in court on June 20.
Those convicted of committing a rash act can be jailed for up to six months and fined up to $2,500.
