Fifty-four people were on the bus when it crashed and no children were killed, US media reported, contradicting an earlier police briefing.
The bus had travelled to Niagara Falls, on the border with Canada, for the day and was heading home when the accident took place on a highway near Pembroke.
Mechanical error ‘ruled out’
“Mechanical error was ruled out as well as impairment or intoxication,” Ray said, adding that no charges had been brought.
Translators were sent to the scene to help communicate with the victims.
Eight helicopters were involved in the rescue effort, Margaret Ferrentino, president of Mercy Flight, a nonprofit provider of air ambulance services, told AFP.
“The driver is alive and well – we’re working with him. We believe we have a good idea of what happened, why the bus lost control. We just want to make sure that all the details are thoroughly vetted,” a police spokesman said earlier.
State Governor Kathy Hochul said her team were co-ordinating with state police and local officials “who are working to rescue and provide assistance to everyone involved”.
Blood and organ donor network Connect Life issued a call for blood donors to come forward after the crash.
“I’m heartbroken for all those we’ve lost and all those injured and praying for their families. Thank you to our brave first responders on the scene,” said the senior US senator from New York, Chuck Schumer.
Niagara Falls – towering waterfalls that span the US-Canada border – is a popular tourist destination.
