We found your daughter. Come now.
The call, from a Singapore Civil Defence Force (SCDF) officer at 11am last Wednesday, was chilling.
It drove Mr Mahesh Chulliparambil and his wife into a panic.
They rushed to a carpark at Bishan Street 11, where they were told their daughter had been found.
Their three-and-a-half-year-old girl had been trapped in her school bus after she could not get off when it was at her kindergarten.
Yesterday Mr Mahesh, 41, an IT project manager, told The New Paper that his wife had watched their daughter clamber on to the school bus from the void deck of their Punggol HDB block at 7.50am that day.
But when the bus arrived at the Global Indian International School in Balestier, his daughter did not get off as she had trouble with her seat belt.
"She didn't know what do," said Mr Mahesh. "She couldn't get the belt off and she didn't think to alert the driver about it.
"But she was very strong. She remained calm and didn't cry at all."
Mr Mahesh added that the driver did not check if everyone had left the bus before driving off.
There was also no attendant on the bus that day, he said.
This was confirmed by ComfortDelgro, which had outsourced the service to a private operator.
