Two of the four people who allegedly wrecked Heng Long Teochew Porridge restaurant in Upper Serangoon Road after an early morning meal landed in court yesterday.

Pang Pei Pei, 40, and Tan Sung Meng, 46, were each charged with one count of committing a rash act by throwing bowls, tables and chairs in the eatery at around 3.45am last Saturday. They allegedly committed the offence with Mr Ang Sim Poh.

Police are still investigating him, and have yet to arrest the fourth man.

In a news statement on Tuesday, police said officers from the Ang Mo Kio Police Division had arrested three people, including a woman, aged between 40 and 53 over two days from last Monday for their suspected involvement in the ruckus.

The incident allegedly erupted after a group of customers at the restaurant became upset with the $28 bill they were given for their meal of porridge, pomfret and several side dishes.

A cleaner had said the customers threw furniture and other items after arguing with a staff member.

An 80-second video of the alleged incident was later uploaded online and showed at least three people picking up objects such as chairs before flinging them onto a food counter.

After the incident, staff closed the outlet temporarily and cleaned up the place.

The restaurant was back in business by noon that day.

Pang is represented by lawyers K. Ravendra and Tay Hao Ran from Vision Law. Mr Ravendra told District Judge Kan Shuk Weng that his client, who has a five-month-old baby daughter, probably has post- natal depression.

He also said the girl needs her mother, and Pang needs to sort out her family arrangements.

Judge Kan said Pang had told the investigation officer that she had gone to the Institute of Mental Health for treatment, but had not been following up on it. The judge also said she had not been taking her medication.

Pang and Tan are out on bail of $5,000 each.

She will be back in court on June 7. Tan, who is unrepresented, will be back in court on June 21.

Those convicted of committing a rash act can be jailed for up to six months and fined up to $2,500.

The Straits Times visited the eatery yesterday and was told by staff that business had returned to normal.

"The damage from the incident reached $5,000 as we had to replace tables, chairs and broken glass," one of the managers, who declined to be named, told The Straits Times.

The eatery is frequented by students and office workers, as well as people who live in the neighbourhood.
