Witness says: When the "green man" signal came on, the elderly woman started pushing her shopping cart across the road.
Just as she got to the other side of the road, a loud crash startled her.
Madam Tey Kah Git, 66, a retiree, turned around and what she saw horrified her: A car had knocked into two boys who, just seconds ago, were walking just behind her.
The accident happened in front of Block 401 at Tampines Avenue 7 at 10.10am on Sunday.
Madam Tey was on her way home from the nearby Shop N Save supermarket. She was walking in front of the two boys - who are understood to be brothers - as she crossed the two-lane road.
One of the boys fell at the black Mitsubishi's front right wheel.
The impact threw the other into the air. He landed face-down about a metre away.
"His nose and mouth were bleeding very badly," Madam Tey told The New Paper yesterday.
"One of his legs also looked injured," she added.
Too shakened by the accident to render assistance, she stood by the roadside as other passers-by gathered to help.
She said: "I was so scared, I was shivering all the way home."
One eyewitness, who wanted to be known only as Mr Tan, said he was waiting at the pedestrian crossing with his family.
He said: "We thought he would stop, but he didn't. Maybe he couldn't brake in time."
Mr Tan, who is unemployed, said the driver helped the boy who was lying face-down to the grass patch at the road divider.
The other boy was able to get up on his own.
Mr Tan said the driver then allegedly got back into his car.
"I told him that the police hadn't even arrived yet, but he said he would come back. In the end, he didn't," said Mr Tan.
Madam Tey said she, too, was shocked that he drove off.
She said: "He should have waited for the police to come. It was very irresponsible of him to drive off."
The police issued a news release on Sunday, reminding motorists that under the Road Traffic Act, anyone involved in an accident cannot leave the scene.
First-time offenders can be fined $3,000 or be jailed up to a year.
Repeated offenders can be fined $5,000 or jailed for up to two years.
Mr Tan said he handed his mobile phone to one of the boys so that the boy could contact his mother.
She arrived in about five minutes.
By then, there were about 10 passers-by at the scene.
