SINGAPORE - He had gone to a playground in Potong Pasir to meet a boy who was allegedly bullying his younger brother and threatening to beat him up.
Mr Baldwin Singh, 18, said the teenager showed up with a friend and walked towards him holding a plastic bag.
When the boy got closer, he lunged at Mr Singh with the plastic bag.
The nursing student could not react in time and the impact of the bag hitting his chest made him stumble backwards.
When he felt a wet and warm sensation on the left side of his chest and saw that he was bleeding heavily, he realised that he had been stabbed with a knife hidden in the bag, Mr Singh told The New Paper yesterday in his Potong Pasir home.
"I immediately shouted 'knife, knife, knife' to warn my younger brother and my schoolmate, who were present," he added.
"As I ran away, my attacker chased me. But he was delayed by my friend who tried to stop him."
The incident occurred on July 4 afternoon near Block 147, Potong Pasir Avenue 1.
As Mr Singh dashed to a clinic about 100m from where he was attacked, the front of his blue shirt and pants was soaked in blood.
At The Family Practice clinic, a doctor tried to stem the bleeding by applying pressure on the wound using a bandage while waiting for an ambulance and the police to arrive.
The victim's father, Mr Baldave Singh, told TNP that the two boys involved in the attack followed his son to the clinic and waited outside.
The father of three sons said he was deeply disturbed by what he learnt from shopkeepers in the area.
"Some of them told me that the two boys were seen laughing outside the clinic as though nothing serious had happened," said the 53-year-old taxi driver.
When TNP went to the scene yesterday, a witness said that she had seen at least one of the boys, who was wearing a black shirt, "smiling and looking relaxed".
The employee at Homemaker Employment Services said: "They sat near the flower pots outside my office. The one in school uniform looked a little worried. But not the other boy in black."
By the time Mr Baldave Singh received word of the attack, his son had been taken to Tan Tock Seng Hospital in an ambulance.
"Doctors at the hospital told me the knife narrowly missed my son's heart, by 3cm. By God's grace, my son is alive today," he said.
The alleged attacker had apparently threatened to beat up his youngest son, Jeet, 13.
It is believed that Jeet and the alleged attacker are from the same secondary school in the neighbourhood.
All Mr Baldwin Singh could remember was the boy in school uniform approaching him and lunging at him with the plastic bag.
"I didn't see the knife. But I knew I had to stop the bleeding before I passed out," he said.
