A Pennsylvania-based charter bus company says it continues to work with the RCMP as they investigate a fatal crash last weekend in Cape Breton.

Executive Coach says its thoughts remain with the 20 passengers who were aboard the tour bus and their families.

A 70-year-old woman from Pennsylvania was killed when the bus landed on its side in a ditch south of Neils Harbour on Sunday.

Police have said 10 people were hurt in the crash.

Executive Coach says as many as five passengers remained in hospital Thursday.

It says it will work with the injured tourists to arrange transportation home when they are able to travel.

The RCMP have ruled out mechanical failure as a contributing factor in the crash.
