This is the heart-wrenching video of a dad saying goodbye to his teenage son as he boards a bus to a football tournament that ended with the boy’s death.

On the drive home, Kaylon da Silva Paixao was one of four killed when the coach plunged off a 10-metre- (33-foot-) high bridge.

Footage filmed by dad Gilson shows shy Kaylon waving to the camera before getting on the bus.

In the video, Kaylon – wearing a grey-and-white T-shirt – simply smiles and waves as he steps up through the bus doors.

Grieving Gilson said at his son’s funeral in Mage, Brazil, on 31st January: “I took him, we said our prayers. He doesn’t like being filmed.

“He got on, I filmed my son’s last little goodbye. I even said to him, ‘Dad loves you.'”

The accident happened on a stretch of the BR-116 motorway in Alem Paraiba early on 30th January.

Kaylon was part of the Vila Maria Helena team that had just won the under-16 football championship in Ubaporanga.

Paramedic Guilherme Ferreira Rodrigues said at the time: “They were returning from a tournament where they were champions and unfortunately, this happened.

“They were happy and most of them still had their medals around their necks.”

As well as Kaylon, 15-year-olds Thyago Ramos de Oliveira and Andrey Viana da Costa, and Diogo Coutinho Vilar, 18, lost their lives in the plunge.

Dad Gilson tearily recalled: “He said, ‘Dad, I’m going to come back with the medal.’

“My little son said, ‘Dad, I’m going to make you, my mum and my friends in the neighbourhood proud.'”

He took aim at the bus driver, saying: “An experienced driver doesn’t put a bus on at that time, the children had just finished playing, not only my son but his other teammates who also died.”

The driver has denied accusations that he was speeding. He claims he was cut up by a lorry before losing control of the steering.

As well as the four dead, 29 were injured when the bus – which was heading to Duque de Caxias – landed on its roof.

They were taken to hospitals in Alem Paraiba and Leopoldina, where some are still in intensive care units.

Civil Police are investigating the case.
