The student who was stabbed at Potong Pasir last Thursday is recovering well and was transferred out of the high-dependency ward into a general ward at Tan Tock Seng Hospital.
A report in The Straits Times said that the doctors had at first been concerned about the accumulation of blood and fluid in 17-year-old Raffles Institution student Anand Ravindran's chest, and said he might need major surgery.
However, doctors said he will not need an operation after all and the English daily was told that he could go back to rugby in about three months.
When reporters from The Straits Times visited the teenager yesterday, he was in good spirits and there was a stream of visitors by his side.
Friends and family described the first-year A-level student as outgoing, friendly and popular in school.
Anand and his friend, Don Tan from St Andrew's Secondary School, also 17, were allegedly attacked by a group of teenagers at the void deck of Block 122, in Potong Pasir Ave 1. Anand was stabbed and Don suffered a bruise eye.
A staring incident had allegedly sparked off the attack.
Five teens have since been arrested and have been charged in court for rioting armed with a deadly weapon.
The Straits Times reported that Liong Hong Ting, 18; Lim Ming Yi, 17; Terrence Chue Wee Teck, 17; and Isaac Ang Shi Ming, 16, were taken to court in a police van.
The youngest, a 15-year-old boy, cannot be named.
They were arrested within six hours after a police report was made.
The four older teens are remanded in police custody for further investigations while the 15-year-old has been sent to a boys' home.
If convicted, they could be jailed up to 10 years and caned.
