Police have arrested the last of four people who allegedly wrecked Heng Long Teochew Porridge restaurant in Upper Serangoon Road last weekend.
Ang Sim Poh, 48, was nabbed on Thursday and charged in court yesterday with committing a rash act.
Only two other suspects have been charged in court.
Ang, Pang Pei Pei, 40, and Tan Sung Meng, 46, are accused of throwing bowls, tables and chairs in the eatery at around 3.45am on May 27. Pang and Tan were each charged on Wednesday with one count of performing a rash act. Police are still investigating the case against Mr Yeoh Keng Hock, 53, and he has not been charged.
Pang, Tan and Mr Yeoh were arrested between Monday and Tuesday. In a statement, the police said officers are also investigating Ang for mischief - causing damage of $500 or more - at the restaurant.
The ruckus last weekend allegedly erupted after a group of diners became upset with the $28 bill they were given 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, who is represented by lawyer Rajan Supramaniam from Hilborne Law, is out on bail of $5,000.
Pang and Tan were each bailed out for the same amount on Wednesday. Pang will be back in court next Wednesday. The cases involving Ang and Tan have been adjourned to June 21.
Those convicted of committing a rash act can be jailed for up to six months and fined up to $2,500.
