(CNSNews.com) - Greyhound says the bus crash that killed six passengers and injured 34 others on board was the "result of an isolated act by a single deranged individual," a man carrying a Croatian passport, who slashed the throat of the bus driver Wednesday morning in rural Tennessee.
The bus driver lost control on I-24 in Manchester, Tenn. A woman on the bus told a Nashville television station that the man who attacked the driver was acting strangely, repeatedly asking what time it was. The driver was treated for a cut to his neck and was stable after surgery, according to a hospital official.
"Our condolences go to the families and friends of the passengers that were hurt and injured and all of the people involved in the incident and the drivers as well," said Craig Lynch, head of Greyhound bus lines.
The bus originated in Chicago and was on its way to Orlando, Fla., carrying 38 passengers and a driver on board, Lynch said.
Greyhound bus service was suspended nationwide Wednesday morning after the accident, but was resumed at 1 p.m.
"It's safe to resume service for our customers and necessary to resume service for our country," Lynch said. "The system is safe, but we understand that in the aftermath that our employees and passengers may not wish to return to the buses today."
He offered an alternative to customers good for Wednesday only.
"To address...this situation in order to offer maximum choice and convenience for our customers today we will be offering a full refund to any passenger who does not wish to travel to their destination," Lynch said.
He also announced that Greyhound ticket holders may exchange their ticket for an Amtrak ticket "to be used for service on any Northeast corridor unreserved train and other trains in the Amtrak system on a space available basis" for Wednesday only.
Lynch said he determined that the accident was "an isolated incident" after consulting with senior officials at the Department of Transportation, the acting administrator of the Federal Motorcarrier Safety Administration, law enforcement officials in Tennessee and the FBI.
