Sydney police are searching for two boys who rode on the roof of a bus through the city’s east.

Footage of the incident at 11.40am yesterday shows the teenagers lying on the roof of the 356 bus as it drove from Eastgardens to Bondi Junction.

The pair can be seen perched near the vehicle’s rooftop emergency exit hatch.

The driver stopped the vehicle at Queens Park where the two teenagers immediately got off the vehicle.

Riding on a bus roof – known as ‘bus surfing’ – is an illegal and dangerous act that has become popularised on social media.

But transport authorities have condemned the pair yesterday for their recklessness, and say they’re determined to stamp it out.

“There’s nothing harmless about this type of behaviour. It endangers lives and disrupts the safety of our transport network,” said Transport for NSW coordinator-general Howard Collins.

“We’re committed to working closely with police to put a stop to it.

“Too often, it’s young people getting caught up in this, and they’re putting themselves and others at serious risk.”

Collins also warned ‘bus surfers’ they risk serious injury or death by striking overhead wires or other infrastructure, such as bridges,

“This could be the last decision you ever make.”
